Question

split the middle term x2,-8x-1280​

Answer 1

This is quadratic equation and you can solve this by using formula or by solving this equation.

By solving equation you have like this

x^2−8x−1280=0

x^2–40x+32x-1280=0

x(x-40)+32(x-40)=0

(x-40)(x+32)=0

x=40 or -32

And if you use formula

40Then a=1,b=-8 and c=-1280

By putting these all in above equation you get two value of x

ie x=40 or x=-32.

Thank you.
