(2x+3)(3x+6)=0
We multiply parentheses ..
(+6x^2+12x+9x+18)=0
We get rid of parentheses
6x^2+12x+9x+18=0
We add all the numbers together, and all the variables
6x^2+21x+18=0
a = 6; b = 21; c = +18;
Δ = b2-4ac
Δ = 212-4·6·18
Δ = 9
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{9}=3$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(21)-3}{2*6}=\frac{-24}{12} =-2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(21)+3}{2*6}=\frac{-18}{12} =-1+1/2 $
