7 A^{2} - 11 A - 6 = 0

A = 2, A = - \frac{3}{7}

Decimal Notation

A = 2, A = - 0.42857 \dots

Solution steps

7 A^{2} - 11 A - 6 = 0

Solve with the quadratic formula

A_{1, 2} = \frac{- ( - 11 ) \pm ( - 11 ) ^{2} - 4 \cdot 7 ( - 6 )}{2 \cdot 7}

(- 11)^{2} - 4 \cdot 7 (- 6) = 17

A_{1, 2} = \frac{- ( - 11 ) \pm 17}{2 \cdot 7}

Separate the solutions

A_{1} = \frac{- ( - 11 ) + 17}{2 \cdot 7}, A_{2} = \frac{- ( - 11 ) - 17}{2 \cdot 7}

A = \frac{- ( - 11 ) + 17}{2 \cdot 7} : 2

A = \frac{- ( - 11 ) - 17}{2 \cdot 7} : - \frac{3}{7}

The solutions to the quadratic equation are:

A = 2, A = - \frac{3}{7}

3 (2 x + 8)^{2} + 18 = 45

x = 2 x^{2} - 1

v^{2} = - 64

x^{2} + 2 x + 1 = 4 x^{2} - 12 x + 9

0 = 3 x^{2} - 48
