Answer:
6a² - a - 12
Step-by-step explanation:
FOIL Method.
First (2a * 3a) = 6a²
Outer (2a * 4) = 8a
Inner (-3 * 3a) = -9a
Last (-3 * 4) = -12
6a² + 8a - 9a -12
6a² - a - 12
Answer:
[tex]6a^2-a-12[/tex]
Step-by-step explanation:
we have the expression:
[tex](2a - 3)(3a + 4)[/tex]
to solve this problem we need to multiply the elements of the first parenthesis (2a -3) by the elements of the second parenthesis (3a + 4), and we will get the following:
[tex](2a - 3)(3a + 4)=2a*3a+2a*4-3*3a-3*4[/tex]
and simplifying the resulting expression we get:
[tex](2a - 3)(3a + 4)=6a^2+8a-9a-12[/tex]
finally, putting together like terms, we get the answer in standard form:
[tex](2a - 3)(3a + 4)=6a^2-a-12[/tex]
