Given the numerical expression:
(2 m + 3) (m - 1)
Determine the equivalent expression.
Solution:
In order to find the answer for the expression, we use the FOIL Method.
se the FOIL method in solving for the given numerical expression. Multiply the first term of the first equation, to the first and last term of the second equation. Then, multiply the last term of the first equation, to the first and last term of the second equation.
To clearly see how it works, here's a step by step solution.
= (2m)(m)
=2m^2
First term of the first equation multiplied to the first term of the second equation.
=(2m)(-1)
= -2m
First term of the first equation multiplied to the last term of the second equation.
=(3)(m)
=3m
Last term of the first equation multiplied to the first term of the second equation.
=(3)(-1)
= -3
Last term of the first equation multiplied to the fast term of the second equation.
= 2m^2 -2m + 3m -3
= 2m^2 + m -3
Final answer:
= 2m^2 + m -3
