Rewrite the expression by factoring out (v-4).<br> 7v2(v - 4) – 3(v-4)
Shtirlitz [24]

Answer:

(7v²-3)(v-4)

Step-by-step explanation:

Rewrite the expression by factoring out (v-4).

7v²(v - 4) – 3(v-4)

Since (v-4) is common to both terms, we only pick one of it to have a factored form:

(7v²-3)(v-4)

The new expression will be (7v²-3)(v-4)
