# how do you factor the polynomial x^2+3x-4 (answer)

Factoring a polynomial of the form ax2 + bx + c is the process of manipulating the previous expression so that its new form is something like (_x + _)(_x + _), where your job is to fill in the blanks.  This may look confusing at first, but a numerical example will help...

# Using the formula A=lw, find the area of the rectangle. (answer)

This question is about how to handle exponents in terms that are multiplied together.  As a general rule, if you have an expression like xa * xb you can simplify this to xa+b.  In order to demonstrate, let's let a = 2, and b = 3.  In this case we want x2 * x3.  If we remember...

If this is supposed to say x2 + 3x -10 = 0, we can factor this polynomial to help us find the answer.  Factoring the polynomial gives us (x + 5)(x - 2) = 0.  Now, we know that anything multiplied by zero gives us zero, so it can either be the case that (x + 5) = 0, or (x...
