No calculator

The polynomial is already given in factor form

\left(x + 3\right)\left(x + 3\right)\left(x - 1\right)=0

Use the null factor law and state the real roots with their multiplicities

In the following parts, P(x) denotes the polynomial on the left of the displayed equation

(a)1 mark

Determine the complete real solution set of the polynomial equation

Choose the completely factorised zero-form equation, retaining the original leading coefficient

\left(x + 3\right)\left(x^{2} + 2x - 3\right)=0

\left(x + 3\right)\left(x - 1\right)=0

\left(x - 3\right)\left(x - 3\right)\left(x - 1\right)=0

\left(x + 3\right)\left(x + 3\right)\left(x - 1\right)=0

(b)4 marks

Enter the real roots in increasing order and the multiplicity of each root

Root 1 Multiplicity of root 1 Root 2 Multiplicity of root 2
