X^3 + 7x^2 -6x -42
Take out common factors
x^2(x+7) -6(x+7)
group them together (combine the factors you pulled out, which are x^2 and -6 then group them. x+7 is repeated twice so that can be combined into one factor.
final factors:
(x^2-6) (x+7)
Answer:
+2
Step-by-step explanation:
-(-2)
since: same signs gives the positive sign i.e + and different signs gives negative sign -
-×-2
=+2
Answer:
71.875
use long division so the 5.75 goes on top of the 0.08
