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.

Suppose x and y are odd prove xy is odd?
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.

12a2b plus 8a-5a2b plus 2ab - 4ab2 plus 6ab-2a-3ab?
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)

How do you factorise 4ab?
2a(2b) Would Give You The Answer 4ab. 2x2 = 4 And a x b = ab.
Simplify 5a³ - 4ab plus 2a³ as much as possible?
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
What is the answer to 2ax2b?
Oh, dude, you're hitting me with some algebra vibes! So, like, the answer to 2ax2b is just 4abx, you know? It's like you're mixing up those variables and numbers, but it's all good, we'll simplify that expression like it's nothing.
How do you simplify an expression in the format of 4a2 plus 4ab - y2 plus b2?
4a2 + 4ab - y2 + b2 You cannot simplify this expression because it does not contain like terms, but you can factor it such as: 4a2 + 4ab - y2 + b2 = (4a2 + 4ab + b2) - y2 = (2a + b)2 - y2 = [(2a + b) - y][(2a + b) + y]

Which is a factor of 6a2 plus 5ab - 6b2?
Considering the minus sign between 5ab and 6b2 then we have the polynomial as 6a2 + 5ab - 6b2. The polynomial is a quadratic polynomial.Steps to factorize a quadratic polynomial:1 - Multiply first term by third term. 6a2 x (-6b2) = -36a2b22 - If possible break the second term into two terms such that they multiple to -36a2b2. If not then it is factorized by Sridharacharya's formula.5ab can be broken as 9ab + (-4ab).These two terms multiply to give -36a2b2.So we can write 6a2 + 5ab - 6b2 = 6a2 + 9ab + (-4ab) - 6b2.6a2 + 9ab - 4ab - 6b2 = 3a(2a + 3b) - 2b(2a + 3b) = (2a + 3b)(3a - 2b).So the factors are (2a + 3b) and (3a - 2b).
What is 4ab x 3a?
4ab * 3a = 12a2b -----------
How do you factorise 4ab plus 2ac?
5 = 1 x 5, 21 = 3 x 7 3 x 5 = 15, 1 x 7 = 7, 15 - 7 = 8 so: (5x + 7)(x - 3)
Suppose x and y are odd prove xy is odd?
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.
Find the area of a rectangle that has a base of 4a cm and a height of 2a plus b cm?
You have to multiply base x height - in this case, you obtain (4a)(2a+b). This can't be simplified; you can leave it as it is (factored), or multiply it out to obtain 8a2 + 4ab.
