(x+1)(x+1)-(5-4x)(5-4x)=0
We add all the numbers together, and all the variables
(x+1)(x+1)-(-4x+5)(-4x+5)=0
We multiply parentheses ..
(+x^2+x+x+1)-(-4x+5)(-4x+5)=0
We get rid of parentheses
x^2+x+x-(-4x+5)(-4x+5)+1=0
We multiply parentheses ..
x^2-(+16x^2-20x-20x+25)+x+x+1=0
We add all the numbers together, and all the variables
x^2-(+16x^2-20x-20x+25)+2x+1=0
We get rid of parentheses
x^2-16x^2+20x+20x+2x-25+1=0
We add all the numbers together, and all the variables
-15x^2+42x-24=0
a = -15; b = 42; c = -24;
Δ = b2-4ac
Δ = 422-4·(-15)·(-24)
Δ = 324
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{324}=18$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(42)-18}{2*-15}=\frac{-60}{-30} =+2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(42)+18}{2*-15}=\frac{-24}{-30} =4/5 $
