Question

$x { }^{2} - 15x + 54 = 0$
​

Answer 1

Answer:

${x}^{2} - 15x + 54 = 0$

${x}^{2} - 9x - 6x + 54 = 0$

x (x-9) -6 (x-9)=0

(x-9) (x-6) =0

x-9=0 x-6 =0

x=9 or x=6

Answer 2

Answer:

$x^{2} -15x+54=0$

=$x*x-15x+54=0$

=$x*x-15x=-54$

$x*x=-54+15x$

$x=\frac{-54+15x}{x}$

$x=-54+15$

=-39
