Find the value of this expression if x = 4 x^2 -8

Let's solve your equation step-by-step.

x=4x2−8

Step 1: Subtract 4x^2-8 from both sides.

x−(4x2−8)=4x2−8−(4x2−8)

−4x2+x+8=0

For this equation: a=-4, b=1, c=8

−4x2+1x+8=0

Step 2: Use quadratic formula with a=-4, b=1, c=8.

x=−b±√b2−4ac2a

x=−(1)±√(1)2−4(−4)(8)2(−4)

x=−1±√129−8

x=18+−18√129 or x=18+18√129

x=18+−18√129 or x=18+18√129

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
