what is the product of the binomials (4a - 1) and (2b + 3)?\n18ab - 3\n8a^{2}b^{2}+10ab - 3\n6ab + 7a - 2b - 3\n8ab + 12a - 2b - 3
Answer
Explanation:
Step1: Use FOIL method
$(4a - 1)(2b+3)=4a\times2b+4a\times3+(- 1)\times2b+(-1)\times3$
Step2: Calculate each product
$4a\times2b = 8ab$, $4a\times3=12a$, $(-1)\times2b=-2b$, $(-1)\times3 = - 3$
Step3: Combine results
$8ab + 12a-2b - 3$
Answer:
$8ab + 12a-2b - 3$
