This is 2/21. You can simplify the 4 in -4/7 to 2 and the 6 in -1/6 to 3. So it would now be -2/7 times -1/3. A negative times a negative is a positive, so the answer will be positive. 1 times 2 is 2 and 7 times 3 is 21. 2/21

Answer:
6x² + 17x + 12
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor
(3x + 4)(2x + 3)
= 3x(2x + 3) + 4(2x + 3) ← distribute both parenthesis
= 6x² + 9x + 8x + 12 ← collect like terms
= 6x² + 17x + 12 ← in expanded form
