Answer :
The equation by completing the square (x + 7)^2 = 16 or (x - 7)^2 = 16. The solutions to the equation are; A. x = -4 ± 3
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Consider the equation: x^2=-8x-7
1) Rewrite the equation by completing the square. Write it as (x+c)^2=d or (x-c)^2=d
Here the equation: x^2=-8x-7
x^2 + 8x + 7 = 0
Where a = 2, b = 8 , c = 7
(x+c)^2 = d or (x + 7)^2 = 16
(x-c)^2=d or (x - 7)^2 = 16
2) The solutions to the equation are;
A. x = -4 ± 3
