Answers

p(x) = 4√3x² + 5x - 2√3

==> 43x² + 8x - 3x - 23 = 0

==> 4x(3x + 2) - 3(3x + 2) = 0

==> (3x + 2)(4x - 3) = 0

Case-1:

==> √3x + 2 = 0

==> x = -2/√3

==> x =  \sf -\dfrac{2\sqrt{3}}{3}

Case-2:

==> 4x - √3 = 0

==> x =  \sf \dfrac{\sqrt{3}}{4}

Hence, Zeroes of the given polynomial are  \sf -\dfrac{2\sqrt{3}}{3} \: and  \sf \dfrac{\sqrt{3}}{4}

Answer: 4√3 x^2 + 5x - 2√3

= 43 x^2+8x-3x - 23

= 4x(3x+2)-3(3x+2)

= (3x+2)(4x-3)

Roots = 3x+2 = 0

x = -2/3

4x-3 = 0

x = 3/4

Roots are -2/3 and 3/4.
