-3x(2x-5)=15-6x
We move all terms to the left:
-3x(2x-5)-(15-6x)=0
We add all the numbers together, and all the variables
-3x(2x-5)-(-6x+15)=0
We multiply parentheses
-6x^2+15x-(-6x+15)=0
We get rid of parentheses
-6x^2+15x+6x-15=0
We add all the numbers together, and all the variables
-6x^2+21x-15=0
a = -6; b = 21; c = -15;
Δ = b2-4ac
Δ = 212-4·(-6)·(-15)
Δ = 81
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{81}=9$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(21)-9}{2*-6}=\frac{-30}{-12} =2+1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(21)+9}{2*-6}=\frac{-12}{-12} =1 $
