Raise $x - 1$ to the power of $1$ .

$(x - 1) (x - 1) (3 x - 2) (x + 3) = 0$

Step 2.1.4.3

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

${(x - 1)}^{1 + 1} (3 x - 2) (x + 3) = 0$

Step 2.1.4.4

Add $1$ and $1$ .

${(x - 1)}^{2} (3 x - 2) (x + 3) = 0$

Step 2.2

If any individual factor on the left side of the equation is equal to $0$ , the entire expression will be equal to $0$ .

${(x - 1)}^{2} = 0$

$3 x - 2 = 0$

$x + 3 = 0$
