x^{2} - 16 x + 3 x = 90

x = 18, x = - 5

Solution steps

x^{2} - 16 x + 3 x = 90

Refine

x^{2} - 13 x = 90

Move

90

to the left side

x^{2} - 13 x - 90 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 1 \cdot ( - 90 )}{2 \cdot 1}

(- 13)^{2} - 4 \cdot 1 \cdot (- 90) = 23

x_{1, 2} = \frac{- ( - 13 ) \pm 23}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 13 ) + 23}{2 \cdot 1}, x_{2} = \frac{- ( - 13 ) - 23}{2 \cdot 1}

x = \frac{- ( - 13 ) + 23}{2 \cdot 1} : 18

x = \frac{- ( - 13 ) - 23}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

x = 18, x = - 5

x (x + 4) = - 5

5 x^{2} + 3 x + 10 = 0

5 x^{2} + 12 x - 20 = - 3 x

x, x - y = x^{2} - y^{2}

2 x^{2} + 22 x = - 60
