Question

factorise the following by splitting the middle term

15 t square - 2 t -1

​

Answer 1

Step by step explanation:

15t^2 - 2t - 1

[rough just for explanation 15×1=15,so we need that numbers when we multiply them we get 15 and when we add or subtract them, we get -2 and the numbers are 3 and 5]

by middle term splitting,

$15t ^{2} + 3t - 5t - 1$

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

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