Polynomials Functions

Convert to intercept form (hint: factor completely, GROUPING) y = 2x³ + 7x² - 2x - 7

• cannot be factored

• y =(x - 1)²(2x + 7)

• y=(x² - 1)(2x + 7)

• y=(x + 1)(x - 1)(2x + 7)

What is the factored form of a function if it has zeros of 2, 3 and -1?

• (x-2)(x-3)(x+1)

• (x-1)(x-2)(x-3)

• (x-1)(x+2)(x+3)

• (x+1)(x+2)(x+3)
