For this case we must find the product of the following expressions:
\frac {3x} {x + 1} * \frac {x} {x-7}
So:
\frac {3x ^ 2} {x ^ 2-7x + x-7} =\\\frac {3x ^ 2} {x ^ 2-6x-7}
So, we have to:
\frac {3x} {x + 1} * \frac {x} {x-7} = \frac {3x ^ 2} {x ^ 2-6x-7}
Answer:
\frac {3x ^ 2} {x ^ 2-6x-7}
Step-by-step explanation:
Step 1
(((((3•(a2))•b)+5ab)-4ab)+(a•(b2)))+(23a2•b)
step 2
((((3a2 • b) + 5ab) - 4ab) + ab2) + 23a2b
step 3
Pull out like factors :
11a2b + ab2 + ab = ab • (11a + b + 1)
step 4:ans
ab • (11a + b + 1)
