Question

Factor the expression v² - v - 20 into TWO binomials.

Answer 1

Answer:

(v+4)(v-5)

Step-by-step explanation:

Given expression:

• v² - v - 20

We have to factor into two binomials.

Solution:

Binomials are any polynomials with 2 terms.

We can simply factor it using middle term factor theorem:

• v² -v -20

As -5*+4 = 20 and v has a negative sign,so:

• v² - (5-4)v - 20
• v² - 5v+4v -20
• v(v-5) + 4(v-5) [Factor out the common terms]
• (v+4)(v-5)[Factor out (v-5)]

There you go! We have expressed it into two binomials.
