4 x^{2} - 13 x = 56

x = \frac{13 + 1065}{8}, x = \frac{13 - 1065}{8}

Decimal Notation

x = 5.70429 \dots, x = - 2.45429 \dots

Solution steps

4 x^{2} - 13 x = 56

Move

56

to the left side

4 x^{2} - 13 x - 56 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 4 ( - 56 )}{2 \cdot 4}

(- 13)^{2} - 4 \cdot 4 (- 56) = 1065

x_{1, 2} = \frac{- ( - 13 ) \pm 1065}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- ( - 13 ) + 1065}{2 \cdot 4}, x_{2} = \frac{- ( - 13 ) - 1065}{2 \cdot 4}

x = \frac{- ( - 13 ) + 1065}{2 \cdot 4} : \frac{13 + 1065}{8}

x = \frac{- ( - 13 ) - 1065}{2 \cdot 4} : \frac{13 - 1065}{8}

The solutions to the quadratic equation are:

x = \frac{13 + 1065}{8}, x = \frac{13 - 1065}{8}

x, x^{2} + k x + x = 8 + k

(x - 5)^{2} - 3 = 0

x^{2} - 4 x + 13 = 0.2 + 3 i

- 3 x^{2} - 298 = - 60 x - 1

w (2 w - 11) - 8 = 0
