Answer:

a = 4

b = - 7

c = 1

x = 1.5 or x = 0.25

Step-by-step explanation:

4x² - 7x + 1 = 0

This equation is the form of

ax² + bx + c = 0.

Here,

a = 4

b = - 7

c = 1

Let the Discriminant be " D ".

D = b² - 4ac

= ( - 7 )² - 4 ( 4 ) ( 1 )

= 49 - 16

D = 25

x = ( - b ± √D ) / 2a

= ( - ( - 7 ) ± √25 ) ) / 2 ( 4 )

= ( 7 ± 5 ) / 8

= ( 7 + 5 ) / 8, ( 7 - 5 ) / 8

= 12 / 8, 2 / 8

x = 1.5, 0.25

x = 1.5 or x = 0.25
a = 4
b = -7
c = 1
