X^2+6x-16=0 solve each equation by completing the square
Rama09 [41]

The solution of the equation is x=2 and x=-8

Explanation:

Given that the equation is x^{2}+6 x-16=0

We need to determine the solution of the equation by completing the square.

Thus, we have,

x^{2}+6 x-16=0

Adding both sides of the equation by 16, we get,

x^{2}+6 x=16

Let us solve by completing the square.

To bring the equation in the form of x^{2}+2 a x+a^{2}=(x+a)^{2}, let us add a^{2}=3^{2} to both of the equations.

Thus, we have,

x^{2}+6 x+3^{2}=16+3^{2}

Simplifying, we get,

(x+3)^{2}=25

Taking square root on both sides of the equation, we get,

x+3=\pm5

Thus, the two solutions of the quadratic equation are

x+3=5 and x+3=-5

Simplifying the two values, we get,

x=2 and x=-8

Thus, the roots of the equation are x=2 and x=-8
