Question

factorize the polynomial (y2-2y + 5) &(y² - 2y +3 - ) -35.​

Answer 1

Answer:

Hey,

You can find the answer below!

Step-by-step explanation:

2y

3

+y

2

−2y−1

=2y

3

+2y

2

−y

2

−y−y−1

=2y

2

(y+1)−y(y+1)−1(y+1)

=(y+1){2y

2

−y−1}

=(y+1){2y

2

−2y+y−1}

=(y+1){2y(y−1)+1(y−1)}

=(y−1)(y+1)(2y+1)

Answer 2

Answer:

Step-by-step explanation:

y^2+3y−y−3=0

⇒y(y+3)−1(y+3)=0

taking (y+3)common,

⇒(y+3)(y−1)=0

∴ y+3=0 OR y−1=0

y=−3 OR y=1
