Multiplying Polynomials. How do we find the area of a square?. The correct formula is written above. Use it to find the area of the square below. As we have already said, to find the area, we square the length of a side. .
Use it to find the area of the square below.
square the length of a side.
We have already seen that 2(x+1) = 2x+2
We were able to do this multiplication by using the
distributive property. We can also use the
distributive property when we are multiplying
polynomials by polynomials.
term in the first set of parentheses through
the second set of parentheses.
1.) (x+2) (x+8)
2.) (x+5) (x-7)
3.) (2x+4) (2x-3)
1.) (x+2) (x+8) = X2+10x+16
2.) (x+5) (x-7) = X2-2x-35
3.) (2x+4) (2x-3) = 4x2+2x-12
(x+1)(x2+2x+3) = X3+2x2+3x+x2+2x+3
