Question

if x is equal to 1 by 2 + root 3 find the value of x square minus x square minus 11x + 3​

Answer 1

Answer:

x= 5/4

Step-by-step explanation:

ATQ    $x=\frac{1}{2} + \sqrt{3}$

$x^{2} = (\frac{1}{2} + \sqrt{3} )^2$

$x^{2} = \frac{1}{4} + 3 +3$

$x^{2} = \frac{1}{4} + \frac{12}{4} +\frac{12}{4}$

$x^{2} =\frac{25}{4}$

$x=\sqrt{\frac{25}{4} }$

$x=\frac{5}{4}$
