Step-by-step explanation:
Factor by grouping.
f(x) = x³ + 3x² − 5x − 4
f(x) = x³ + 3x² − 4x − x − 4
f(x) = x (x² + 3x − 4) − (x + 4)
f(x) = x (x − 1) (x + 4) − (x + 4)
f(x) = (x² − x) (x + 4) − (x + 4)
f(x) = (x² − x − 1) (x + 4)
Answer:
3t-9
Step-by-step explanation:
First we take the product of 3 and t.
Which is 3xt=3t.
Now 9 less that product of 3and t is 3t-9.

Hope this helps!
Yes it is correct because if you multiply 3 by the value of x(7) and add 4 your answer is 25.
