Question

the solution set of equation x^2 -4x -12 = 0

Answer 1

It is a quadratic equation x^2-2x+2x-12=0

Answer 2

Answer:

Solution of x are -2 and 6

Step-by-step explanation:

This can be solved by using the method of Splitting the middle term or you can use the Quadratic Formula

Let is solve by splitting the middle term

x^2 -4x -12 = 0

=> x^2 -6x+2x -12 = 0 [by splitting -4x]

Now lets take common

=> x(x-6)+2(x-6) = 0

=> (x+2)(x-6) =0

=> (x+2) = 0 or (x-6) = 0

=> x = -2 or x = 6

So Solution of x are -2 and 6
