Divide the product by one of the multiplicands. The answer should be the other multiplicand.
monomial
When multiplying exponential factors the exponents are added if bases are the same. 5^3 * 5^4 = 5^7 check it out on your calculator.
You make a check by they're name, then go to delete.
(3b - 1)(a - b)
(a - 2b)(c - 3d)
150
(2a + 3)(b - 3c)
The expression, as given, cannot be factorised.
I suppose you mean factoring the polynomial. You can check by multiplying the factors - the result should be the original polynomial.
