Well, isn't that a happy little math problem we have here? To solve 4ab x 2a, you simply multiply the numbers together. First, multiply the numbers: 4 x 2 = 8. Then, multiply the variables: a x a = a^2, and b x nothing is just b. So, the final answer is 8a^2b. Just like painting a beautiful landscape, math can be a lovely and calming experience when you break it down step by step.
To solve the expression 4ab x 2a, we first multiply the coefficients 4 and 2 to get 8. Next, we multiply the variables a and a to get a^2. Finally, we multiply the remaining variable b to get the final answer of 8a^2b.
Well, honey, 4ab times 2a is 8a²b. Multiply those terms like a boss and you'll get your answer. Math doesn't have to be a headache, just buckle down and crunch those numbers.
4ab - 2a - 7
4ab * 3a = 12a2b -----------
Write x and y in terms of integers, which we call a and b. For some integer, x = 2a + 1 y = 2b + 1 Multiplying them, you get: xy = (2a+1)(2b+1) = 4ab + 2a + 2b + 1 Since the first terms are even, adding one makes the final result odd.
4a2+4ab+b2 in2
Assuming that non-leading numbers are exponents, the expression becomes12a^2b + 8a - 5a^2b + 2ab - 4ab^2 + 6ab - 2a - 3ab= 7a^2b + 6a + 5ab - 4ab^2= a*(7ab + 6 + 5b - 4b^2)
