Question

X^2+10x+21/x^2+8x+15

Answer 1

\[\frac{x^2+10x + 21}{x^2 + 8x + 15}\]

Answer 2

yea

Answer 3

\[\frac{x^2 + 7x + 3x + 21}{x^2 + 3x + 5x + 15}\]

Answer 4

\[\frac{x(x+7)+3(x+7)}{x(x+3)+5(x+3)}\]

Answer 5

X^2+10x+21/x^2+8x+15

x^2 +10x +21 = (x+7) (x+3)
x^2 +8x + 15 = (x+3)(x+5)

X^2+10x+21/x^2+8x+15
= (x+7)(x+3)/ (x+3)(x+5) = (x+7)/(x+5)

Answer 6

\[\frac{(x+7)(x+3)}{(x+5)(x+3)}\]

Answer 7

(3 (6 x^3+5 x^2+7))/x^2+X^2

Answer 8

x+3's cancel

Answer 9

Final Answer:

\[\frac{x+7}{x+5}\]
