How do you solve the quadratic equation #4x^2 - 8x + 1= 0# by using the Quadratic Formula?
2 Answers
Using quadratic formula:
Explanation:
you assume the value
=> 4 to be your ''a''
=> -8 to be your ''b''
=> 1 to be your ''c''
Now just replace the values in the formula, and obtain your two values
-> N.B You will obtain two values (might be one positive one and the other, a negative one)
Explanation:
#color(blue)(4x^2-8x+1=0#
This is a Quadratic equation (in form
Use Quadratic equation
#color(brown)(x=(-b+-sqrt(b^2-4ac))/(2a)#
Note:
So,
#color(purple)(a=4,b=-8,c=1#
Remember that
Which implies that
#color(indigo)(x=((2+sqrt3)/(2),(2-sqrt3)/(2))#
