Question

Factor 5v^2 - 23v - 10​

Answer 1

Answer:

$(5v + 2)(v - 5)$

Step-by-step explanation:

Hello!

The expression is written in the form of $ax^2 + bx + c$

Let's factor by grouping:

$ac = -50$

The sum of the factors of -50 should add up to -23.

-25 and 2 work for this.

Expand and factor:

• $5v^2 - 23v - 10$
• $5v^2 - 25v + 2v - 10$
• $5v(v - 5) +2(v -5 )$
• $(5v + 2)(v - 5)$

The factored expression is $(5v + 2)(v - 5)$
