Answer: The product of (3x+7) and (x-7) equals 3x^2 + 28x + 49
Step-by-step explanation:
To find the product of (3x+7) and (x-7) means to multiply both variables: To multiply both variables, we first multiply 3x by the expression, x - 7, then multiply 7 by the expression, x - 7.
(3x * x) + (3x * 7) + (7 * x) + (7 * 7)
= 3x^2 + 21x + 7x + 49
= 3x^2 + 28x + 49
