Question

What is the solution set for the quadratic equation 4x^2 - 25 = 0

Answer 1

X=2.5
X=-2.5
I think.
I hope this helps!

Answer 2

Throw -25 on the other side making it 4x^2 = 25
Then, divide 4 on both sides making it x^2 = 25/4
Now square root both sides, and get your answer
x = +/- (plus or minus) 5/2.

Hope this helps!
