Question

Solve the following quadratic equation for all values of xx in simplest form.

5(2x+1)^2+6=26 cant figure this out!!

Answer 1

x=1/2 and x=-3/2

Explanation:

5(2x+1)^2+6=26

5(2x+1)^2=20

(2x+1)^2=4

2x+1=±2

Now make two equations and solve both for x:

2x+1=2

2x=1

x1=1/2

2x+1=-2

2x=-3

x2=-3/2
