Question

simplify ( y^2 - 7y+4) ( 3y^2 -2) + ( y-1) ( y^2- 2y) ​

Answer 1

Given :–

• An equation, (y² – 7y + 4)(3y² – 2) + (y – 1)(y² – 2y)

To Find :–

• Simplify the given equation.

Solution :–

The given equation is,

⟹ (y² – 7y + 4)(3y² – 2) + (y – 1)(y² – 2y)

Open the both small brackets.

⟹ [3y⁴ – 21y³ + 10y² – 14y – 8] + [y³ – y² – 2y² – 2y]

Now, open the both big brackets,

⟹ 3y⁴ – 21y³ + 10y² – 14y – 8 + y³ – y² – 2y² – 2y

Arrange the same variable numbers,

⟹ 3y⁴ – 21y³ + y³ + 10y² – 3y² – 14y – 2y – 8

Now, solve this.

We obtain,

⟹ 3y⁴ – 20y³ + 7y² – 16y – 8

Hence,

The simplified equation of the given equation (y² – 7y + 4)(3y² – 2) + (y – 1)(y² – 2y) is 3y⁴ – 20y³ + 7y² – 16y – 8.

Answer 2

Answer:

$\huge\text {heya}$

Answer to your question:-

→(y²-7y+4)(3y²-2y)+(y²+1)(y²+2y)

=>3y⁴-2y²-21y³+14y+12y²-8+y³+2y²+y²+2y

=>3y⁴+13y²-20y³+16y-8

So, this is the answer

Hope helped!!
