Question

48+2
$48 + 2x - x2$


​

Answer 1

Step-by-step explanation:

$- {x}^{2} + 2x + 48 = 0 \\ - {x}^{2} + 8x - 6x + 48 = 0 \\ - x(x - 8) - 6(x - 8) = 0 \\ (x - 8)( - x - 6) = 0 \\ x - 8 = 0 = = > x = 8 \\ - x - 6 = 0 = = > x = - 6$

Answer 2

$\mathsf{ - {x}^{2} + 2x + 48 = 0} \\ \\ \mathsf{ - {x}^{2} + 8x - 6x + 48 = 0} \\ \\ \mathsf{ - x(x - 8) - 6(x - 8) = 0} \\ \\ \mathsf{ (x - 8)( - x - 6) = 0} \\ \\ \mathsf{ x - 8 = 0 \: \: \: | \: \: x = 8 }\\ \\ \mathsf{ - x - 6 = 0 \: \: \: | \: \: x = - 6} \\ \\ \boxed{ \mathsf{x \: = \: 8 \: , \: - 6}}$
