Question

do this sum with proper steps....​

Answer 1

This is the answer to the first two questions.

The third question is not valid if ther is no variable, as an equation can't be formed without any variable. So I have taken the variable as I , which in the question looks like 1. here is your answer:

Answer 2

Factorize:

1) $[y^{2} + 7y +10] / y+5$

By using factorisation method in the quadratic equation,

we would get, [ y + 5 ] [ y + 2 ]

By dividing it by [y+5],

we will get answer i.e, [y+2]

2) $[5p^{2} -25p+20]/[p-1]$

The first step is to multiply 5 to the constant term i.e, 20.

we'll get 100.

So, lets factorise the quadratic equation, $5p^{2} -25p+100$

Then, refer the attachment.

After the factorisation,

we will get answer i.e, [p-4][p-1]

dividing by p-1,

we will get answer that is, [p-5]

Kindly, The third question is incorrect and lacks sufficient information.
