Solve the quadratic equation. 1) 4x2 - 36 = 0

Step-by-step explanation:

welll i think tha answer is = 6-36 =0

= -30

4x^2 - 36 = 0   ( Original equation )

4x^2 = 36        ( Add 36 to both sides )

x^2 = 9            ( Divide by 4 on both sides )

x = 3 , -3          ( Take the square root of 9 )

Solution set: { +3 , -3 } answer is x = +3 , x = -3
