Question

(y+1)*(y+1)-4y*(y+1)

Answer 1

Ответ:

y²+y+y+1-4y²-4y= -2y-3y²+1

Answer 2

Ответ:

$y^{2} +y+y+1-4y^{2}-4y=-3y^{2} -2y+1$

Answer 3

Let's simplify the expression:

(y + 1) * (y + 1) - 4y * (y + 1)

Using the distributive property, we can expand the expression:

= (y + 1) * (y + 1) - 4y * (y + 1) = (y^2 + 2y + 1) - 4y * (y + 1)

Now, we can simplify further by multiplying the terms:

= y^2 + 2y + 1 - 4y^2 - 4y = -3y^2 - 2y + 1

So, the simplified expression is -3y^2 - 2y + 1.
