Question

(x+7)^2 + (2x+2)^2


solve x

Answer 1

Hi friend here is your answer

(x + 7)² + (2x + 2)²

using the identity :

(a + b)² = a² + b² + 2ab

so we get ,

(x² + (7)² + 2 × x × 7) + ((2x)² + (2)²

(x² + 49 + 14x) + (4x² + 4 + 8x)

5x² + 22x + 53

on middle term splitting

we get ,

two roots of x

and that will be your answer.
