NEED ASAP!! let f(x)= x^4- 7x^3 +13x^2+3x-18. READ BELOW

Question

f(x) = x⁴- 7x³ +13x²+ 3x -18. Given that 3 is a zero of f with multiplicity 2, solve the equation x⁴ -7x³ +13x² +3x -18 =0

Use quadratic formula.

Answer 1

f(x) = (x - 3)²(x - a)(x - b)

Multiply out (x - 3)².

Divide f(x) by the product
