Answer:
The required expression is 7n²+89n+60
Step-by-step explanation
To get the expression, we will multiply the two linear expression by opening the bracket to give a quadratic equation.
(n + 12) x (5+7n)
We will use the variable and the constant of n + 12 to multiply that of 5+7n to give;
(n + 12)(5+7n) = 5n + 7n² + 60 + 84n
Rearranging the equation gotten we will have;
7n²+84n+5n+60
= 7n²+89n+60 which is the required quadratic expression.
Is there any answer choices? I need the expressions to see which is equivalent to <span>(n + 12) x 5+7n</span>
