-5x(-x-1)+4x=49
We move all terms to the left:
-5x(-x-1)+4x-(49)=0
We add all the numbers together, and all the variables
-5x(-1x-1)+4x-49=0
We add all the numbers together, and all the variables
4x-5x(-1x-1)-49=0
We multiply parentheses
5x^2+4x+5x-49=0
We add all the numbers together, and all the variables
5x^2+9x-49=0
a = 5; b = 9; c = -49;
Δ = b2-4ac
Δ = 92-4·5·(-49)
Δ = 1061
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-\sqrt{1061}}{2*5}=\frac{-9-\sqrt{1061}}{10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+\sqrt{1061}}{2*5}=\frac{-9+\sqrt{1061}}{10} $
