(16+2x)(12+2x)=185
We move all terms to the left:
(16+2x)(12+2x)-(185)=0
We add all the numbers together, and all the variables
(2x+16)(2x+12)-185=0
We multiply parentheses ..
(+4x^2+24x+32x+192)-185=0
We get rid of parentheses
4x^2+24x+32x+192-185=0
We add all the numbers together, and all the variables
4x^2+56x+7=0
a = 4; b = 56; c = +7;
Δ = b2-4ac
Δ = 562-4·4·7
Δ = 3024
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{3024}=\sqrt{144*21}=\sqrt{144}*\sqrt{21}=12\sqrt{21}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(56)-12\sqrt{21}}{2*4}=\frac{-56-12\sqrt{21}}{8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(56)+12\sqrt{21}}{2*4}=\frac{-56+12\sqrt{21}}{8} $
