x^{2} - 55 x = 56

x = 56, x = - 1

Solution steps

x^{2} - 55 x = 56

Move

56

to the left side

x^{2} - 55 x - 56 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 55 ) \pm ( - 55 ) ^{2} - 4 \cdot 1 \cdot ( - 56 )}{2 \cdot 1}

(- 55)^{2} - 4 \cdot 1 \cdot (- 56) = 57

x_{1, 2} = \frac{- ( - 55 ) \pm 57}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 55 ) + 57}{2 \cdot 1}, x_{2} = \frac{- ( - 55 ) - 57}{2 \cdot 1}

x = \frac{- ( - 55 ) + 57}{2 \cdot 1} : 56

x = \frac{- ( - 55 ) - 57}{2 \cdot 1} : - 1

The solutions to the quadratic equation are:

x = 56, x = - 1

x, f (x + h) = 2 (x + h)^{2} + 5 (x + h) - 3

x^{2} + 0.05 x + 0.0004 = 0

x^{2} + 1.8 \cdot 1 0^{- 5} x - 3.6 \cdot 1 0^{- 7} = 0

y^{2} - 14 y + 4 = 0

(2 x + 3) (4 x + 5) = 0
