Option A
The equation [tex]4x^2 - 3x + 1 = 0[/tex] has two imaginary solutions
Solution:
Given that we have to determine the type and number of solutions of given quadratic equation
[tex]4x^2 - 3x + 1 = 0[/tex]
[tex]\text {For a quadratic equation } a x^{2}+b x+c=0, \text { where } a \neq 0\\\\x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]
In a quadratic equation, the discriminant helps tell you the number of real solutions to a quadratic equation
In the case of a quadratic equation [tex]ax^2 + bx + c = 0[/tex], the discriminant is [tex]b^2 -4ac[/tex]
[tex]\text{If } b^{2}-4 a c=0 ;$ then the given quadratic equation has one real root\\\\If b^{2}-4 a c>0,$ then the given quadratic equation has two real roots[/tex]
If [tex]b^2-4ac<0[/tex], then the given quadratic equation has two imaginal roots which are complex conjugates
Given quadratic equation is:
[tex]4x^2 - 3x + 1 = 0[/tex]
Here a = 4 and b = -3 and c = 1
The discriminant is given as:
[tex]b^2 - 4ac = (-3)^2 - 4(4)(1) = 9 - 16 = -7\\\\b^2 - 4ac = -7\\\\b^2-4ac < 0[/tex]
Therefore the given equation has two imaginary solutions
