Answer:

Use the distributive property and expand 28, then distribute the 4 to 20 and the 4 to 8. Then you have 18 + 80 + 32. Use commutative property to reverse the order of 32 and 80 so that 18 and 32 are friendly numbers to add.

Answer:

<h2> $- {x}^{4} - 7 {x}^{3} + 8$ </h2>

Step-by-step explanation:

$(5 - 5 {x}^{4} - {x}^{3} ) - (6 {x}^{3} - 4 {x}^{4} - 3)$

Remove unnecessary parentheses

$5 - 5 {x}^{4} - {x}^{3} - (6 {x}^{3} - 4 {x}^{4} - 3)$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression

$5 - 5 {x}^{4} - {x}^{3} - 6 {x}^{3} + 4 {x}^{4} + 3$

Collect like terms

$5 + 3 - 5 {x}^{4} + 4 {x}^{4} - {x}^{3} - 6 {x}^{3}$

$5 + 3 - {x}^{4} - 7 {x}^{3}$

Add the numbers

$8 - {x}^{4} - 7 {x}^{3}$

Use the commutative property to reorder the terms

$- {x}^{4} - 7 {x}^{3} + 8$

Hope this helps...

Best regards!!
