Factor: g^2+13g+30

1 answer

To factor the quadratic expression \( g^2 + 13g + 30 \), we need to find two numbers that multiply to \( 30 \) (the constant term) and add up to \( 13 \) (the coefficient of the \( g \) term).

The pairs of factors of \( 30 \) are:

  • \( 1 \) and \( 30 \)
  • \( 2 \) and \( 15 \)
  • \( 3 \) and \( 10 \)
  • \( 5 \) and \( 6 \)

Among these pairs, the pair that adds up to \( 13 \) is \( 3 \) and \( 10 \).

Now we can write the quadratic in its factored form:

\[ g^2 + 13g + 30 = (g + 3)(g + 10) \]

So the factored form of \( g^2 + 13g + 30 \) is:

\[ (g + 3)(g + 10) \]
