4 x^{2} - 12 x + 9 = 5

x = \frac{3 + 5}{2}, x = \frac{3 - 5}{2}

Solution steps

4 x^{2} - 12 x + 9 = 5

Move

5

to the left side

4 x^{2} - 12 x + 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 4 \cdot 4}{2 \cdot 4}

(- 12)^{2} - 4 \cdot 4 \cdot 4 = 45

x_{1, 2} = \frac{- ( - 12 ) \pm 4 5}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- ( - 12 ) + 4 5}{2 \cdot 4}, x_{2} = \frac{- ( - 12 ) - 4 5}{2 \cdot 4}

x = \frac{- ( - 12 ) + 4 5}{2 \cdot 4} : \frac{3 + 5}{2}

x = \frac{- ( - 12 ) - 4 5}{2 \cdot 4} : \frac{3 - 5}{2}

The solutions to the quadratic equation are:

x = \frac{3 + 5}{2}, x = \frac{3 - 5}{2}
