Answer:
b=-3
Step-by-step explanation:
If the expression simplifies to bx that means the terms and the constant terms must be cancel out.
Simplify it first.
We know –4 + 4 will cancel out. If we simplify this expression to only an x term, then the terms should be cancelled. Therefore, we say that 4ax^2 – x^2 = 0.
If we put a = ¼, then we can find the value of b:
if the expression is equivalent to bx
Therefore, b = –3.
