Please help! I really need help...

Answer:

$3y^{2}+2y-11$

Step-by-step explanation:

we have

$(-y^{2}-4y-8)-(-4y^{2}-6y+3)$

Eliminate the parenthesis

$-y^{2}-4y-8+4y^{2}+6y-3$

Group terms that contain the same variable

$-y^{2}+4y^{2}-4y+6y-8-3$

Combine like terms

$3y^{2}+2y-11$

Simplify the expression: 2x – 3x (5x – 8) – 4r (x - 2)

AVprozaik [17]

Answer: –4rx –15x^2 + 8r + 26x

Step by step:

= 2x + −15x^2 + 24x + −4rx +8r

= (−4rx) + (–15x^2) + (8r) + (2x+ 24x)

= –4rx + –15x^2 + 8r + 26x

Answer please I’m really struggling with this

katovenus [111]

To write the any polynomial in standard form you must first put it in terms separated only by $+,-$ operators, then you must order terms $x^n$ descendingly according to $n$ . In your case $-\frac{1}{5}x^2$ will be the first term because it has highest power, followed by $-8x^1$ and $+7x^0$ .

The standard form of this specific polynomial is:

$-\dfrac{1}{5}x^2-2x+7$ .

Hope this helps.
