Write as a product of two polynomials
a) 3a(2x–7)+5b(7–2x)
b) (x–y)^2–a(y–x)

a) (3a-5b)(2x-7) or (-3a+5b)(7-2x)

b) (x-y)(x-y+a) or (y-x)(y-x-a)

Step-by-step explanation:

a) 3a(2x-7)+5b(-(-7+2x))

3a(2x-7)-5b(2x-7)

(3a-5b)(2x-7)

3a(-(-2x+7))+5b(7-2x)

-3a(7-2x)+5b(7-2x)

(-3a+5b)(7-2x)

b)(x-y)^2-a(-(-y+x))

(x-y)^2+a(x-y)

(x-y)(x-y+a)

(-1(-x+y))^2-a(y-x)

(1(y-x)^2-a(y-x)

(y-x)(y-x-a)

step-by-step explanation:

its a wood chuck that can chuck wood

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
