Solving Polynomial Word Problems Pre Calculus

Give the equation of the 4th degree polynomial with zeros: 1 with multiplicity 2 and i.

• x² - 4x + 4

• x³ - 4x² + 4x +ix² -4ix + 4i

• x⁴ - 4x³ + 5x²-4x + 4

• x⁴ - 4x³ + 5x²-4x + 4i

• y =  ^_(x + 2)(x - 1)²
• y = -(x - 2)(x + 1)²
• y = (x - 2)(x + 1)²
• y = -x³

Match the equation to the graph.

• y=-(x+1)(x-2)(x-4)

• y=(x+1)²(x-3)(x-1)³

• y = 3x³ – 2x + 1

• y=(x+1)³(x-3)(x-1)²
