(2x+3)(5x+7)=119
We move all terms to the left:
(2x+3)(5x+7)-(119)=0
We multiply parentheses ..
(+10x^2+14x+15x+21)-119=0
We get rid of parentheses
10x^2+14x+15x+21-119=0
We add all the numbers together, and all the variables
10x^2+29x-98=0
a = 10; b = 29; c = -98;
Δ = b2-4ac
Δ = 292-4·10·(-98)
Δ = 4761
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{4761}=69$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(29)-69}{2*10}=\frac{-98}{20} =-4+9/10 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(29)+69}{2*10}=\frac{40}{20} =2 $
