Step 2.1.1

Simplify.

$(t - 8) {(t - 4)}^{2} {(t - 2)}^{3} {(t - 1)}^{4} = 0$

Step 2.1.2

Apply the distributive property.

$(t {(t - 4)}^{2} - 8 {(t - 4)}^{2}) {(t - 2)}^{3} {(t - 1)}^{4} = 0$

Step 2.1.3

Apply the distributive property.

$(t {(t - 4)}^{2} {(t - 2)}^{3} - 8 {(t - 4)}^{2} {(t - 2)}^{3}) {(t - 1)}^{4} = 0$

Step 2.1.4

Apply the distributive property.

$t {(t - 4)}^{2} {(t - 2)}^{3} {(t - 1)}^{4} - 8 {(t - 4)}^{2} {(t - 2)}^{3} {(t - 1)}^{4} = 0$

Step 2.2

Factor ${(t - 4)}^{2} {(t - 2)}^{3} {(t - 1)}^{4}$ out of $t {(t - 4)}^{2} {(t - 2)}^{3} {(t - 1)}^{4} - 8 {(t - 4)}^{2} {(t - 2)}^{3} {(t - 1)}^{4}$ .
