Question

F(x) = square root 2x - 36

Answer 1

x=18

step by step explanation:

1. group all constants on the right side.

2x-36=0

add 36 on both sides.

(2x-36)+36=0+36

simplify the arithmetic.

2x-0+36

2x-36

2. Isolate the x.

2x-36

divide both sides by 2.

(2x)/2=36/2

find the greatest comman factor.

x=(18x2)/(1x2)

factor our and cancel the greatest comman factor.

x=18
