azamat

Answer:

$(x + 7) * (3x + 1) = (3x^2 + 22x + 7)$

Step-by-step explanation:

Given

$(3x^2 + 22x + 7) \div (x + 7) = 3x + 1$

$(x + 7) * (\ ) = [\ ]$

Required

Complete the blanks

We have:

$(3x^2 + 22x + 7) \div (x + 7) = 3x + 1$

Rewrite as:

$\frac{(3x^2 + 22x + 7) }{ (x + 7)} = 3x + 1$

Cross multiply

$(x + 7) * (3x + 1) = (3x^2 + 22x + 7)$
