Question

x² - 10x + 9 middle term splitting?

Answer 1

Answer:

Step-by-step explanation:

X²-10 X+9 =0

PRODUCT = 9

SUM = -10

NUMBERS:-1 AND -9.

X²-X-9 X+9 =0

X(X-1) -9(X-1) =0

(X-9)(X-1)=0

X-9 =0

X= 9

X-1 = 0

X=1.

THEREFORE :

X= 9 OR X=1.

HOPE THIS HELPS.

Answer 2

Answer:

$\implies x^{2}-10x+9 \\ \implies x^{2}-9x+x+9 \\ \implies x(x-9)+1(x+9) \\ \implies(x-9)(x+1) \\ x=9 and x=-1$
