The question is asking for what the value of a is for the given polynomial.
They gave you a factor to that polynomial, (x+a), and told you that a can be any real number beside 0.
You might remember that when you factor an equation, all you're doing is finding for what value of x will give you an answer of 0.
This is what you're doing now but in reverse. You're given x+a as a factor, so you know that x=-a will make the function equal 0.
So plug x=-a into the function and solve for a. You'd find that you get a=0 and a=2; however, the question stated that a≠0, so the only answer left is a=2.
Here, you have to foil the equation.
Distribute 4x to all sides, then distribute the -3 to all sides. Next, combine like terms. If you do this, your answer will be
Answer: In step 1, he should have added .75x to both sides.
Answer:
1/5
Step-by-step explanation:
There is an easy way I learned.
You can multiply 1/2 by 5/5
so you get 5/10 - 3/10
and the you subtract 5-3=2
2/10
simplify 1/5
