Polynomial Review for Midterm

VIDEO REVIEW This video reviews how to add and subtract polynomials. You should also have notes from Foundations of Math 1 if you need additional help. Please show your work on a separate sheet of paper and attach it to the last question on this assignment.Subtract.

(Hint: Distribute and then combine like terms.)4(x - 3) + 2(x + 5) 6x + 2 6x + 10 6x - 2 6x - 22 Simplify (Hint: Multiply the coefficients and ADD exponents, ex 2x(3x4) = 6x5)2x(3x4 + 4x3 - 3x) 6x4 + 8x3 - 3x 6x5 + 8x4 - 3x2 6x5 + 8x4 - 6x2 6x4 + 8x3 - 6x2 Simplify3x2 (4x - 5x4 - 7x5) 12x3 - 15x6 - 21x7 7x3 - 8x6 - 10x7 12x2 - 15x8 - 21x10 7x2 - 8x8 - 10x10 If a rectangle has a perimeter of 4x + 10 and the width is x + 2, what is the length? x+3 2x+6 6x+12 3x+8 MULTIPLYING BINOMIALS Here is a quick video to remind you how to multiply binomials. We want to use the box to help us. Match these binomials times binomials. Note: x^2 means x2 . (x + 8) (x - 6) x^2 + 2x -48 (x - 6) (x - 6) x^2 -12x + 36 (x + 8) (x + 6) x^2 + 14x + 48 (x + 6) (x - 6) x^2 - 36 Find the area and perimeter of the following rectangle.Remember that perimeter means to add all of the sides and area means to multiply the length times the width. Find the area and perimeter of the following rectangle.Remember that perimeter means to add all of the sides and area means to multiply the length times the width.
