What are the solutions to the polynomial:  p(x)=(2x-1)(x² +3x +1) 
(Hint: Use quadratic formula for x²+3x+1)

• x=1/2, (-3+√5)/2, (-3-√5)/2
• x=1/2, (3+√5)/2, (3-√5)/2
• x=-1/2, (-3+√5)/2, (-3-√5)/2
• x=-1/2, (3+√5)/2, (3-√5)/2

State the zeros of the polynomial (include multiplicity):
f(x) = x(x+3)²(x - 2)

• x = 0, 3, 2
• x = 0, -3 (multiplicity of 2), 2
• -3, 2
• 0, 2 (multiplicity of 3)
