Question

What is the product of (3x+7) and (x-7) ?

Answer 1

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
