Question

If x*x+2x-35=0then x=?​

Answer 1

Answer:

The given equation is a quadratic equation. I'll be solving it by completing the square.

x² + 2x - 35 = 0

x² + 2x = 35

x² + 2(x)(1) = 35

Adding 1² on both sides,

x² + 2(x)(1) + 1² = 35 + 1 = 36

Now compare L.H.S to: a² + 2ab + b² = (a+b)²

So,

(x + 1)² = 36

x + 1 = ±√36

x = ±6 -1

Therefore, the two possible values of x are:

i) x = 6 - 1 = 5

ii) x = 6 + 1 = 7
