Answer:
-21/32
Step-by-step explanation:
It's easier to do this multiplication mentally if we rewrite the expression as follows:
-3 7 -21
------ * ------ = ---------
4 8 32
Lets first take out the GCF of the numbers, we get
3 ( 4a^2 - 12ab + 9b^2)
= 3 ( 2a - 3b)(2a - 3b)
That's it
2x+3=17
subtract 3 from both sides
2x=14
divide both sides by 2 and get
x=7
