Factor x^2-6x-9

factor

x^{2} - 6 x - 9

(x - 3 (1 + 2)) (x + 3 (2 - 1))

Solution steps

x^{2} - 6 x - 9

Solve

x^{2} - 6 x - 9 = 0 : x = 3 (1 + 2), x = 3 (1 - 2)

Polynom can therefore be factored into

= (x - (3 (1 + 2))) (x - (3 (1 - 2)))

Refine

= (x - 3 (1 + 2)) (x - 3 (1 - 2))

Factor

1 - 2 : - (2 - 1)

= (x - 3 (1 + 2)) (x - (- 3 (2 - 1)))

Apply rule

- (- a) = a

= (x - 3 (1 + 2)) (x + 3 (2 - 1))

100/50

\frac{10}{( 2 )}

a

i = 1 \sum 16 5 i - 4

\frac{20}{3}
