Step-by-step explanation:
3m²-3m-18
this is an expression because no equal to sign is present.
To solve this quadratic expression, one will firstly multiply the coefficient of m² with -18
3 * (-18) = -54
factor of 54
1, 2, 3, 6, 9, 18, 27, 54
which two numbers that when added = -3 and when multiplied = -54
the numbers are -9 and 6
substituting 6m - 9m for -3m in the expression
3m² + 6m - 9m - 18
factorize
(3m²+6m)(-9m-18)
3m(m+2)-9(m+2)
(3m-9)(m+2)
thus ANSWER = 3(m-3)(m+2)
