Question

answer my question very very fastanswer question number 35th ​

Answer 1

Answer:

a) $\frac{32p^4 - 1 + p^2}{32}$

b) y^4 - 42 + y^2

Step-by-step explanation - part (a)

$(p^2 - \frac{1}{4} ) (p^2 + \frac{1}{8} )\\= p^2(p^2 +\frac{1}{8} ) - \frac{1}{4} (p^2 + \frac{1}{8} )\\= p^4 + \frac{p^2}{8} - \frac{p^2}{4} - \frac{1}{32} \\= p^4 - \frac{1}{32} - \frac{p^2 - 2p^2}{8} \\= p^4 - \frac{1}{32} + \frac{p^2}{8}$

After this (optional):

$\frac{32p^4 - 1 + p^2}{32}$

Step-by-step explanation - part (b)

$(y^2 - 6) (y^2 + 7)\\= y^2(y^2 + 7) - 6(y^2 + 7)\\= y^4 + 7y^2 - 6y^2 - 42\\= y^4 - 42 + y^2$

That's it :)

Hope this helps :D
