Factor the expression using distributive property: 72b + 45
ANTONII [103]
The answer would be 9(8b+5)
this is how you do it...
1. find the GCF of both numbers in this one the GCF would be 9 
now, what do you multiply 9 by to get 72... 8, so 8 would go into the parenthesis and because there is a variable there which is 'b' the 8 would become '8b' now what do you multiply 9 with to get 45? '5' so you would add 5 into the parenthesis and that would be your answer!

Hope this helped! :D

PLEASE HELP! I AM REALLY CONFUSED! find the value of a if X^3+8x^2+ax-2 is divisible by x-1
WARRIOR [948]

The value of a from the equation is -63.

Here we have to find the value of a.

Given data:

The equation is = x³ + 8x² + ax -2

The equation is divisible by x -1

So we have:

x -1 = 0

x = 1

Now putting the value in the equation we get the remainder as o because the equation is divisible by x -1.

So;

1³ + 8² + a(1) - 2 = 0

63 + a = 0

a = -63

Therefore we get the value of a as -63.
