Factorise completely
x²-7x=12

undefined

Step-by-step explanation:

x²-7x=12

we make the equation equal to zero by subtracting 12 from both sides, we have..

x²-7x-12 = 12-12

x²-7x-12= 0

we find the factors of 12 such that when we multiply them we will get -12 and when we add them we will get -7, and those factors are but those values are not possible..

so answer = undefined
