Answer 2

Answer:

☆ Given - 8x = 57^2 - 33^2

☆ To find - value of x

☆ Solution -

8x = 57^2 - 33^2

Using identity a^2 - b^2 = ( a+ b )(a- b)

8x = (57 + 33 )( 57- 33)

8x = (90 )( 24)

8x = 90 × 24

8x = 2160

x = 2160 / 8

x = 270

Some more identity -

(a+ b)^2 = a^2 + b^2 + 2ab

(a-b)^2 = a^2 + b^2 - 2ab

(x+ a) (x+ b) = x^2 +( a + b) x + ab
