Factorization is the process of expressing an algebraic expression as a product of its factors. To factorize the quadratic expression \(a^2 + 3a - 18 = 0\), we need to find two binomials whose product gives this expression.
The given quadratic expression can be factorized as \((a - 3)(a + 6) = 0\), Since 6*3 is 18 and 6 - 3 is 3.
So, the factorization of \(a^2 + 3a - 18\) is \((a - 3)(a + 6) = 0\).
