Question

Simplify. (2a4+(5a+6)−a2)−(7a−(6a3−2a2+5a)−4(a+6)) Enter the expression in simplest form.

Answer 1

(2a⁴ + (5a + 6) − a²) − (7a − (6a³ − 2a² + 5a) − 4(a + 6)) Let's start by removing what () we can and distributing:

2a⁴ + 5a + 6 − a² + (-7a + (6a³ − 2a² + 5a) + (4(a+6))

2a⁴ + 5a + 6 − a² -7a + 6a³ − 2a² + 5a + 4a + 24

 

Now that we have all our terms, we can start combining like ones

2a⁴ + 5a + 6 − a² -7a + 6a³ − 2a² + 5a + 4a + 24

 

2a⁴ + 6a³ - 3a² + 7a +30
