Answer 1

HEY MATE!

HERE IS YOUR ANSWER:

STEP BY STEP EXPLANATION

First step: put the equation equal to zero

Second step: Look for any common variable present in equation.

Third step : now, start factorizing for that variable

let us take (a) part i.e 12x+9

putting it equal to zero

we have a variable here x so, we need to find value for x

i.e 12x+9=0

12x=-9

x=-9/12=-3/4

we need to follow same procedure in part (b)

now, in (d) part i.e 8ax+12a-4az

putting it equal to zero

i.e 8ax+12a- 4az=0

here we have a common variable "a"so, we need to find the value for a

so, let us take a as common

i.e a(8x+12-4z)=0

As we need to find value of a we cannot take it to the Right hand side, if take it the value of 8x+12-4z will be equal to zero and hence we will be able to find a .

So, let us take 8x+12-4z value to right hand side .

so, a=0/8x+12-4z

now, a become 0

i.e a=0

we need to follow same procedure in part (c)and (e)
