Solve Using the Quadratic Formula 4x^2-64=0

Solution

4 x^{2} - 64 = 0

Solution

x = 4, x = - 4

Solution steps

4 x^{2} - 64 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 0 \pm 0 ^{2} - 4 \cdot 4 ( - 64 )}{2 \cdot 4}

0^{2} - 4 \cdot 4 (- 64) = 32

x_{1, 2} = \frac{- 0 \pm 32}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- 0 + 32}{2 \cdot 4}, x_{2} = \frac{- 0 - 32}{2 \cdot 4}

x = \frac{- 0 + 32}{2 \cdot 4} : 4

x = \frac{- 0 - 32}{2 \cdot 4} : - 4

The solutions to the quadratic equation are:

x = 4, x = - 4
