Find the value of x for the rectangle

perimeter=26 meters

rectangle one the bottom is (x+3) m

on the right side of the rectangle (2x-6) m

(x+3) (2x-6) = 26

2x (to the second power) - 18=26

2x (to the second power) - 18-26=26-26

2x (to the second power) - 44 = 0

x=square root of 22, x = negative square root of 22

decimal form : x = 4.69042, x = - 4.69042
