Question

Factorise:8y²-6y-5
pls say​

Answer 1

Step-by-step explanation:

8y^2-6y-5

=8y^2+4y-10y-5

=4y(2y+1)-5(2y+1)

=(4y-5)(2y+1)

Answer 2

Step-by-step explanation:

the best way to factorise is to multiply first and the last term.

So, we will be multiplying the terms,

its 40, after multiplying try to add or subtract nos. whose difference is 6 and their multiplication gives u 40.

= 8y²-10y+4y-5 // splitting the middle term

= 2y(4y-5)+(4y-5) // taking out the common terms

=

= (4y-5) (2y+1) // the final terms are

Hope it helps.
