Answer:
2a⁴ - За³ - 9а² - 89a + 267
Step-by-step explanation:
Even though the question is not clear, because I do not see any question, I will give this a try...
2a3 + За2 - а - 89
а - 3
I will interpret is as this:
( 2a3 + За2 - а - 89 ) muliply this with (а - 3) and write down the result.
Write in a different form
( 2a³ + За² - 89 ) * ( a - 3 )
( a - 3 ) * ( 2a³ + За² - 89 )
Use the FOIL Method
The FOIL method is made up of four multiplication steps.
To use the FOIL method, the first thing you need to do is place each of the binomials in its own parentheses. Next, using the FOIL method, multiply the first terms from each binomial together. Now, multiply the outside terms of each binomial together. Then, multiply the inside terms together. Finally, multiply the last terms of each binomial together.
a * ( 2a³ + За² - 89 ) -3 * ( 2a³ + За² - 89 )
{ 2a⁴ + За³ - 89a } { - 6a³ - 9а² + 267 }
If possible, take the same terms together:
2a⁴ + { За³ - 6a³ } - 9а² - 89a + 267
2a⁴ - За³ - 9а² - 89a + 267
