Question

factorise 15t square - 2T - 1​

Answer 1

Step-by-step explanation:

15t2 - 2t - 1

15t2 - 5t + 3t - 1

5t(3t - 1 ) +1 ( 3t - 1 )

Answer 2

This question is very easy. It is related to factorisation, so we can solve this by middle term factorisation.

Here we go:-

=15t²-2t-1

(Expand the middle term.)

=15t²-5t+3t-1

(Take out commons.)

=5t(3t-1)+1(3t-1)

=(5t+1) (3t-1)

So, the answer is (5t+1) (3t-1)
