Question

factorise 10y²+11y-6​

Answer 1

Step-by-step explanation:

6 is factorise in that way if we(+)it or(-)the answer will 11y.

1. 3×2=6 but 3+2=5 not 11( we will add 'y ' after getting proper number )
2. So ,we Will multiple 10y²×6=60y²
3. Now we will factorise 60=2×2×3×5(by two - two pair of this four numbers (2×2),(3×5).
4. 4
5. 15y-4y=11y
6. (10y²+15y )(-4y-6)(now we will find the common multiples)
7. 5y(2y+3) -2(2y+3)(if the number and the variable in the bracket are same when your step is right)
8. (the last step is write the bracket one time and the number which is outside the bracket write in this form )= (5y-2)(2y+3)
9. The answer is (5y-2)(2y+3).

I hope this may help you.
