X^{2} + 16 X + 63 = 0

X = - 7, X = - 9

Solution steps

X^{2} + 16 X + 63 = 0

Solve with the quadratic formula

X_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 \cdot 1 \cdot 63}{2 \cdot 1}

1 6^{2} - 4 \cdot 1 \cdot 63 = 2

X_{1, 2} = \frac{- 16 \pm 2}{2 \cdot 1}

Separate the solutions

X_{1} = \frac{- 16 + 2}{2 \cdot 1}, X_{2} = \frac{- 16 - 2}{2 \cdot 1}

X = \frac{- 16 + 2}{2 \cdot 1} : - 7

X = \frac{- 16 - 2}{2 \cdot 1} : - 9

The solutions to the quadratic equation are:

X = - 7, X = - 9

y, x^{2} + (y - 1)^{2} = 1

(1 + 3 x)^{2} = 5 x + 9

5 x^{2} - 25 x - 20 = 0

x (x + 3) - 3 = 0

a^{2} + 7 a - 8 = 0
