Answer:
I can't solve and show it but only tell a method to do it!
So find the zero of the given factor:
i.e.

Now put its value (-1) in the polynomial

Now if the answer comes zero it is a factor.
You'll get your answer!
Answer:
10^22
Step-by-step explanation:
= (10^11)(10^11) -> the bases are the same, add the exponents
= 10^22
In y=-2x+7 the graph will rise from right to left while in y=2x+7 the graph will rise from left to right. Which gives us in conclusion of the slope is negative the graph line will rise from right to left and if positive then left to right
Top one is x+3, bottom one is 5
Mutiplying: the product is always 0
