Question

Solve x^2 + 2x - 48 = 0

Answer 1

X = 6

Explanation:

6² = 36

36 + 12 = 48

48 - 8 = 0

Answer 2

x = - 8, x = 6

Explanation:

`{x}^(2) + 2x - 48 = 0 \\ \\ {x}^(2) + 8x - 6x - 48 = 0 \\ \\ x(x + 8) - 6(x + 8) = 0 \\ \\ (x + 8)(x - 6) = 0 \\ \\ x + 8 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 8, \: \: \: \: x = 6 \\`
