5x^2+6x+7=x2+-4x
We move all terms to the left:
5x^2+6x+7-(x2+-4x)=0
We add all the numbers together, and all the variables
5x^2-(+x^2-4x+)+6x+7=0
We get rid of parentheses
5x^2-x^2+4x+6x+7-=0
We add all the numbers together, and all the variables
4x^2+10x=0
a = 4; b = 10; c = 0;
Δ = b2-4ac
Δ = 102-4·4·0
Δ = 100
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{100}=10$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(10)-10}{2*4}=\frac{-20}{8} =-2+1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(10)+10}{2*4}=\frac{0}{8} =0 $
