(3x+11)(5x-7)=0
We multiply parentheses ..
(+15x^2-21x+55x-77)=0
We get rid of parentheses
15x^2-21x+55x-77=0
We add all the numbers together, and all the variables
15x^2+34x-77=0
a = 15; b = 34; c = -77;
Δ = b2-4ac
Δ = 342-4·15·(-77)
Δ = 5776
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{5776}=76$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(34)-76}{2*15}=\frac{-110}{30} =-3+2/3 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(34)+76}{2*15}=\frac{42}{30} =1+2/5 $
