5p^2+13p-6. Factor

1 answer

To factor the quadratic expression \(5p^2 + 13p - 6\), we need to find two numbers that multiply to \(5 \times -6 = -30\) and add up to \(13\).

The two numbers that meet these criteria are \(15\) and \(-2\) because:

  • \(15 \times -2 = -30\)
  • \(15 + (-2) = 13\)

Now we can rewrite the middle term of the quadratic expression using these two numbers:

\[ 5p^2 + 15p - 2p - 6 \]

Next, we can group the terms:

\[ (5p^2 + 15p) + (-2p - 6) \]

Factoring out the common factors in each group gives us:

\[ 5p(p + 3) - 2(p + 3) \]

Now we can factor out the common binomial factor \((p + 3)\):

\[ (5p - 2)(p + 3) \]

Thus, the factored form of \(5p^2 + 13p - 6\) is:

\[ (5p - 2)(p + 3) \]
