x^{2} - 6 x + 9 = 64

x = 11, x = - 5

Solution steps

x^{2} - 6 x + 9 = 64

Move

64

to the left side

x^{2} - 6 x - 55 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 1 \cdot ( - 55 )}{2 \cdot 1}

(- 6)^{2} - 4 \cdot 1 \cdot (- 55) = 16

x_{1, 2} = \frac{- ( - 6 ) \pm 16}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 16}{2 \cdot 1}, x_{2} = \frac{- ( - 6 ) - 16}{2 \cdot 1}

x = \frac{- ( - 6 ) + 16}{2 \cdot 1} : 11

x = \frac{- ( - 6 ) - 16}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

x = 11, x = - 5

x^{2} + 7 x + 15 = 0

(x + 7)^{2} = 9

3 x^{2} + 4 x + 7 = - 1

x^{2} - \frac{1}{2} x + 1

(x + 1)^{2} = 11
