my computer wont let me click on that website :/

Answer 8

i will help

Answer 9

OK then here's what the websites says.

15t3+2t2-45t-6

Final result :

(15t + 2) • (t2 - 3)

Step by step solution :

Step 1 :

Simplify 15t3+2t2-45t - 6
Trying to factor by pulling out :

1.1 Factoring: 15t3+2t2-45t-6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 2t2-6
Group 2: 15t3-45t
Pull out from each group separately :

Group 1: (t2-3) • (2)
Group 2: (t2-3) • (15t)
-------------------
Add up :
(t2-3) • (15t+2)
Which is the desired factorization

Trying to factor as a Difference of Squares :

1.2 Factoring: t2-3

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 3 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.


Final result :

(15t + 2) • (t2 - 3)

Answer 10

okay thanks :)
