Question

factorise the following expression 6-5y-y^2​

Answer 1

Answer:

(6+y)(1-y)

Step-by-step explanation:

6-5y-y^2

BY SPITTING THE MIDDLE TERM

6-6y+1y-y^2

6(1-y)+y(1-y)

(6+y)(1-y)

Answer 2

The factor of the  expression $6-5y-y^{2}$ is $(1-y)(y+6)$.

Step-by-step explanation:

Given:

The  expression $6-5y-y^{2}$ .

To Find:

The factor of the  expression $6-5y-y^{2}$.

Solution:

As given,the  expression $6-5y-y^{2}$.

The factor of the expression $6-5y-y^{2}$  $=6-5y-y^{2}$                    

                                                                      $= -(y^{2} +5y-6)$

                                                                      $= -(y^{2} +6y-y-6)$

                                                                       $= -[y^{2} +6y-y-6]\\= -[y(y +6)-1(y+6)]\\= - (y-1)(y+6)\\=(-y+1)(y+6)\\=(1-y)(y+6)$

Thus,the factor of the expression $6-5y-y^{2}$ is $(1-y)(y+6)$.
