Question

solve the following equations by factarism​

Answer 1

Answer:

x^2-9x-6x+54

x(x-9)-6(x-9)

(x-6)(x-9)

Answer 2

Instead of 54, there should be 56, then the answer would be:-

${x}^{2} - 15x + 54 = 0 \\ {x}^{2} - 8x - 7x + 54 = 0 \\ x(x - 8) - 7(x - 8) = 0 \\ (x - 8)(x - 7) = 0 \\ x - 8 = 0 \: or \: x - 7 = 0$

$x = 8 \: or \: x = 7$
