(2x+5)(6-5x)=0
We add all the numbers together, and all the variables
(2x+5)(-5x+6)=0
We multiply parentheses ..
(-10x^2+12x-25x+30)=0
We get rid of parentheses
-10x^2+12x-25x+30=0
We add all the numbers together, and all the variables
-10x^2-13x+30=0
a = -10; b = -13; c = +30;
Δ = b2-4ac
Δ = -132-4·(-10)·30
Δ = 1369
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{1369}=37$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-13)-37}{2*-10}=\frac{-24}{-20} =1+1/5 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-13)+37}{2*-10}=\frac{50}{-20} =-2+1/2 $
