Question

x square - 6 x minus 247 equal to zero find its value

Answer 1

x^2-6x-247=0

=>x^2-19x+13x-247=0

=>x(x-19)+13(x-19)=0

=>(x+13)(x-19)=0

=>x= -13 or x=19

Answer 2

Hey mate!

It is given that,
x^2-6x-247 = 0
=> x^2-19x+13x-247 = 0
=> x(x-19) + 13(x-19) = 0
=> (x+13)(x-19) = 0
=> x = -13, 19.

That's the answer!

Hope it helps :)
