Write each function in standard form:
1. y = (x + 7)(5x + 2)(x - 6)²
Using the first method, the one I think is right, I got:I got the answer, but I am not sure if its right. Because I did it two different ways and got two different answers.
First way, I foiled (x + 7) and (5x + 2), and then foiled (x - 6) and (x - 6). Then I just multiplied the product I got.
Second way, I foiled (x - 6) and (x - 6), then multiplied the product with (5x + 2) and again, I multiplied the product of that with (x + 7).
Is it right??
