Answer:
Solution is : x = 1 ± 0.5√3
Step-by-step explanation:
We have given quadratic equation:
4x² - 8x + 1 = 0
We need to find solution using quadratic formula.
i.e x =
Compare from general quadratic equation ax² + bx + c=0
Here a= 4 , b = -8 and c = 1
∴ x = -(-8)±√((-8)²-4·4·1) / 2·4
x = (8 ±√48 )/8
x = 1 ± 0.5√3 , This is the answer
Answer:
Point (3,-2) and Slope = 5
Option C is correct option.
Step-by-step explanation:
Given the equation , identify the point and slope being used in the problem.
The equation is given in point-slope form
The general equation of point-slope form is:
Where m is slope and (x₁,y₁) is the point
Comparing the given equation with general equation we get
m=5,
x₁=3
y₁=-2
So, Point (3,-2) and Slope = 5
Option C is correct option.
