Solve the following quadratic equation for all value of c i'm simplest form
5(x-2)^2=20

x=-2 and x=0

Step-by-step explanation:

5(x-2)^2 =  20; divide by 5 both sides

(x-2)^2 = 4; take the square root of both sides

(x-2) = ±2, now set it equal to positive 2 and negative 2

x-2 = 2

x=4

AND

x-2 = -2

x=0

The values of x is 0 and 4.

Step-by-step explanation:

You have to divide 5 by both sides;

You have to expand the brackets;

You have to factorize;

Lastly, you have to solve it;

it is b)
