Question

Anyone know this answer

Answer 1

Hi there! The third answer is correct.

To find our answer, we must multiply the functions.

$(x - 2)( {x}^{2} + 5x + 2)$
Now we need to get rid of the parentheses.

${x}^{3} + 5 {x}^{2} + 2x - 2 {x}^{2} - 10x - 4$
Finally we collect terms.

${x}^{3} + 3 {x}^{2} - 8x - 4$
Therefore the third answer is correct.
