Question

middle term splitting x²-33x+90

Answer 1

X^2-30x-3x+90

X (x-30) - 3 (x-30)

(X-3)(X-30)

Answer 2

${x}^{2} - 33x + 90 = 0 \\ \\ = > {x}^{2} - (30 + 3)x + 90 = 0 \\ \\ = > {x}^{2} - 30x - 3x + 90 = 0 \\ \\ = > x(x - 30) - 3(x - 30) = 0 \\ \\ = > (x - 30)(x - 3) = 0$

$x - 30 = 0 \\ \\ x = 30$


$x - 3 = 0 \\ \\ x = 3$
