Question

Find the nature of the roots
'root' 3x^2-5x +7'root'3​

Answer 1

Step-by-step explanation:

given.

$\sqrt{3x {}^{2} } - 5x + 7 \sqrt{3}$

$d = b {}^{2} - 4ac$

$here \: \: \: a = \sqrt{3} \: \: \\ b = - 5 \\ c = 7 \sqrt{3}$

$d = - 5 {}^{2} - 4( \sqrt{3} \times 7 \sqrt{3)}$

$d = 25 - 4( \sqrt{3} \times 7 \sqrt{3} )$

$d = 25 - 4(21)$

$d = 25 - 84$

$d = - 59$

Here D < 0 so the roots are imaginary
