tennetiraj86 please can you help me everyday because I am also teacher from school​

Answer 1

Step-by-step explanation:

$\large\textsf{Question 1:}$

$\textsf{Multiply: (5x-y) (3x²+4xy+y²)}$

$\large\textsf{Solution:}$

⇒ $\textsf{(5x-y) (3x²+4xy+y²)}$

⇒ $\textsf{5x(3x²+4xy+y²) -y(3x²+4xy+y²}$

⇒ $\textsf{15x³+20x²y+5xy²-3x²y-4xy²-y³}$

⇒ $\textsf{15x³-y³+17x²y+xy²}$

$\large\textsf{Question 2:}$

Divide the following:

6p⁴-5p³+8p²-4p+7 by (p+1) o

$\large\textsf{Solution:}$

Refer to above attachment.

$\large\textsf{Question 3:}$

Solve,

$\large\frac{(y + 1) - (2y + 3)}{3 - 2y} = \frac{1}{4}$

$\large\textsf{Solution:}$

⇒ $\large\frac{(y + 1) - (2y + 3)}{3 - 2y} = \frac{1}{4}$

⇒ $\large \frac{y + 1 - 2y - 3}{3 - 2y} = \frac{1}{4}$

⇒ $\large\frac{ - y - 2}{3 - 2y} = \frac{1}{4}$

⇒ -4y - 8 = 3-2y

⇒ -4y+2y = 3+8

⇒ -2y = 11

⇒ y = $\large\frac{ - 11}{2}$
