10th Maths Chapter 4 Solutions
Important Questions on Class 10 Maths Chapter 4
Check whether the following is quadratic equation: (x + 1)² = 2(x – 3)
(x + 1)² = 2(x – 3)
Simplifying the given equation, we get (x + 1)² = 2(x – 3)
⇒ x² + 2x + 1 = 2x – 6
⇒ x² + 7 = 0 or x² + 0x + 7 = 0
This is an equation of type ax² + bx + c = 0.
Hence, the given equation is a quadratic equation.
Represent the following situation in the form of quadratic equation: The product of two consecutive positive integers is 306. We need to find the integers.
Let the first integer = x
Therefore, the second integer = x + 1
Hence, the product = x(x + 1)
According to questions,
x(x + 1) = 306
⇒ x² + x = 306
⇒ x² + x – 306 = 0
Hence, the two consecutive integers satisfies the quadratic equation x² + x – 306 = 0.
In a class test, the sum of Shefali’s marks in Mathematics and English is 30. Had she got 2 marks more in Mathematics and 3 marks less in English, the product of their marks would have been 210. Find her marks in the two subjects.
Let, Shefali’s marks in Mathematics = x
Therefore, Shefali’s marks in English = 30 – x
If she got 2 marks more in Mathematics and 3 marks less in English,
Marks in Mathematics = x + 2
Marks in English = 30 – x – 3
According to questions,
Product = (x + 2)(27 – x) = 210
⇒ 27x – x² + 54 – 2x = 210
⇒(-x)² + 25x – 156 = 0
⇒ x² – 25x + 156 = 0
⇒ x² – 12x – 13x + 156 = 0
⇒ x(x – 12) – 13(x – 12) = 0
⇒ (x – 12)(x – 13) = 0
⇒ (x – 12) = 0 or (x – 13) = 0
Either x = 12 or x = 13
If x = 12 then, marks in Maths = 12 and marks in English = 30 – 12 = 18
If x = 13 then, marks in Maths = 13 and marks in English = 30 – 13 = 1
The difference of squares of two numbers is 180. The square of the smaller number is 8 times the larger number. Find the two numbers.
Let the larger number = x
Let the smaller number = y
Therefore, y² = 8x
According to question,
x² – y² = 180
⇒ x² – 8x = 180 [As y² = 8x]
⇒ x² – 8x – 180 = 0
⇒ x² – 18x + 10x – 180 = 0
⇒ x(x – 18) + 10(x – 18) = 0
⇒ (x – 18)(x + 10) = 0
⇒ (x – 18) = 0 or (x + 10) = 0
Either x = 18 or x = -10
But x ≠ -10 , as x is the larger of two numbers.
So, x = 18 Therefore, the larger number = 18
Hence, the smaller number = y = √144 = 12
Sum of the areas of two squares is 468 m². If the difference of their perimeters is 24 m, find the sides of the two squares.
Let the side of larger square = x m
Let the side of smaller square = y m
According to question,
x² + y² = 468 …(i)
Difference between perimeters,
4x – 4y = 24
⇒ x – y = 6
⇒ x = 6 + y … (ii)
Putting the value of x in equation (i), we get
(y + 6)² + y² = 468
⇒ y² + 12y + 36 + y² = 468
⇒ (2y)² +12y – 432 = 0
⇒ y² + 6y – 216 = 0
⇒ y² + 18y – 12y – 216 = 0
⇒ y(y + 18) – 12(y + 18) = 0
⇒ (y + 18)(y – 12) = 0
⇒ (y + 18) = 0 or (y – 12) = 0
Either y = -18 or y = 12
But, y ≠ -18 , as x is the side of square, which can’t be negative.
So, y = 12
Hence, the side of smaller square = 12 m Putting the value of y in equation (ii), we get Side of larger square = x = y + 6 = 12 + 6 = 18 m

HISTORICAL FACTS!
The word quadratic is derived from the Latin word “Quadratum” which means “A square figure”.
Brahmagupta (an ancient Indian Mathematician)(A.D. 598-665) gave an explicit formula to solve a quadratic equation. Later Sridharacharya (A.D. 1025) derived a formula, now known as the quadratic formula, for solving a quadratic equation by the method of completing the square. An Arab mathematician Al-khwarizni(about A.D. 800) also studied quadratic equations of different types. It is believed that Babylonians were the first to solve quadratic equations. Greek mathematician Euclid developed a geometrical approach for finding lengths, which are nothing but solutions of quadratic equations.
