- 4 x^{2} - 7 x = - 36

x = - 4, x = \frac{9}{4}

Decimal Notation

x = - 4, x = 2.25

Solution steps

- 4 x^{2} - 7 x = - 36

Move

36

to the left side

- 4 x^{2} - 7 x + 36 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 ( - 4 ) \cdot 36}{2 ( - 4 )}

(- 7)^{2} - 4 (- 4) \cdot 36 = 25

x_{1, 2} = \frac{- ( - 7 ) \pm 25}{2 ( - 4 )}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 25}{2 ( - 4 )}, x_{2} = \frac{- ( - 7 ) - 25}{2 ( - 4 )}

x = \frac{- ( - 7 ) + 25}{2 ( - 4 )} : - 4

x = \frac{- ( - 7 ) - 25}{2 ( - 4 )} : \frac{9}{4}

The solutions to the quadratic equation are:

x = - 4, x = \frac{9}{4}

y, x^{2} + y^{2} + 72 = 12 x

5 c^{2} + 12 c + 4 = 0

3 v^{2} - v - 12 = - 6

x^{2} - 16 x = - 73

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