To factorize the expression a²-7ab+12b, you need to find two binomials that, when multiplied together, give you the original expression.
First, look at the coefficient of the squared term, which is 1. This means that the binomials will have an "a" term and an "a" term when multiplied together.
Next, look at the constant term, which is 12b. This means that the binomials will have a "b" term and a "b" term when multiplied together.
Now, you need to find two numbers that multiply to give you 12 and add up to -7. The numbers that satisfy this condition are -3 and -4.
Therefore, the expression can be factorized as follows:
a²-7ab+12b = (a-3b)(a-4b)
