Question

Question Simplify: (-12az2-22³)+(-2a³ +7a²z)-(-4a²z+8az²).

Answer 1

Step-by-step explanation:

if I take the expression as you wrote it literally, we have

(-12az2 - 22³) + (-2a³ + 7a²z) - (-4a²z + 8az²) =

= -24az - 10,648 - 2a³ + 7a²z + 4a²z - 8az² =

= -24az - 10,648 - 2a³ + 11a²z - 8az²

yet when I assume that there were several typos particularly in the first bracket, my guess about the real original expression is

(-12az² - 2a³) + (-2a³ + 7a²z) - (-4a²z + 8az²) =

= -12az² - 2a³ - 2a³ + 7a²z + 4a²z - 8az² =

= -20az² - 4a³ + 11a²z
