To find product

  $(-3t-16)(5t+2)$

Answer to Problem 8.7EP

  $-5t^2-86t-32$

Explanation of Solution

Given information:

  $(-3t-16)(5t+2)$

Calculation:

  $(-3t-16)(5t+2)$

Open brackets

  $=(-3t)(5t+2)+(-16)(5t+2)$

On solving,

  $=(-3t)(5t)+(-3t)(2)+(-16)(5t)+(-16)(2)$

On solving,

  $=-5t^2-6t-80t-32$

On solving,

  $=-5t^2-86t-32$
