Question

x^2+100x-240000
value of x please

Answer 1

By using quadratic formula the value of x is equal to 50( -1+- root97 )

Answer 2

X2 + 100X - 240000
FROM QUADRATIC FORMULA
X= -b +- D/2a, D= root over b2-4ac
here, a= 1, b= 100, c= - 240000
if you calculate we ll get  D= 500
x( +) = - 100 + 500/2
x+= 400/2
x+= 200
now, x- = - 100- 500/2
x- = -600/2
x- = - 300
HENCE THE VALUE OF X WILL BE 200 OR -300.
HOPE IT HELP YOU
