Multiplying polynomials
x (3x+7)
3x( 6x-4)
4x (-3x^2-2x)
6x (x^2-3x+1)
-x (7x^2-5x+8)
xy (2x-3y-4)
-2xy (5x^2+6xy-y^2)
3x^2y (8xy-5x-6)
-5xy^2 (2x^2y^2-3xy+y)

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

What is the value of x in the equation 2(x-4) = 4(2x + 1)?
