Solve the following equations by factorisation method. Only factorisation not dharacharya.

Hello, please consider the following.

When and are two roots, we can factorise as

So for the first equation, we can say that the sum of the zeros is

and the product is

So we can factorise as below.

And the solutions are

For the second equation, we will complete the square and put the constant on the right side and take the root.

Let's do it!

We take the root, and we find the two solutions

Thank you.

the answer is 24

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
