Consider the equations: y = 2x - 2 and y = 3x - 2.
Solve the system of equations by graphing each equation to find an ordered pair that satisfies both equations.

All you need to do is factor the expressions. for a you get (3x+4)^2, so the answer is just 3x+4.  when you factor b, you get 4x-5y and 4x+5y and those are your dimensions.9x²+24x+16=(3x+4)², so each side is 3x+416x²-25y²=(4x+5y)(4x-5y), so one side is 4x+5y, the other side is 4x-5y9x^2 + 24 x + 16 = 0  (3x +4) (3x + 4) =  0x=-4/3b16x^2 - 25y^2 =  0(4x-5y)(4x+5y)= 0
