(X+7)(4X+3)=180
We move all terms to the left:
(X+7)(4X+3)-(180)=0
We multiply parentheses ..
(+4X^2+3X+28X+21)-180=0
We get rid of parentheses
4X^2+3X+28X+21-180=0
We add all the numbers together, and all the variables
4X^2+31X-159=0
a = 4; b = 31; c = -159;
Δ = b2-4ac
Δ = 312-4·4·(-159)
Δ = 3505
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}$$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(31)-\sqrt{3505}}{2*4}=\frac{-31-\sqrt{3505}}{8} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(31)+\sqrt{3505}}{2*4}=\frac{-31+\sqrt{3505}}{8} $
