what are the factor of the following trinomial?

Question

3t^2 + 19t + 6

a) (t + 1)(3t + 6)
b) (3t + 1)(t + 6)
c) (t - 1) (3t + 6)
d) (3t - 1) (t + 6)

Answer 1

If we note that 19=3*6+1*1, we would choose the answer where all signs are positive, and which gives the term 18t².

Answer 2

Look at answer (b).

Step 1.

Multiply 3t by t

Step 2.

Multiply 3t by 6

Step 3.

Multiply 1 by t

Step 4.

Multiply 1 by 6

That gives you

3t^2+18t+t+6

Step 5.

End Result

3t^2 + 19t + 6
