Avg score: 0% • Most missed: “Find the value when the given polynomials 3p and (24x + 14y2) are multiplied.”

Some rules to remember while multiplying algebraic expression are:
- The product of two factors with the same signs will be positive, and the outcome of multiplying two terms with two, unlike signs, will be negative.
- If x is variable and a, b are positive integers then, (xa * xb) = x(m +n)
