Question

if x = 1/ (2 - √3), then find the value of x^2 + 3x - 14

Answer 1

Answer:

13+7root3-14

Step-by-step explanation:

given that x=1/2-root3

on rationalising the factorx=2+root3

to find find x^2+3x-14

put the value of x.

(2+root3)+3 (2+root3)-14

2^2+2 (2)(root3)+(root3)^2+6+3root3-14

calculating further,we get

13+7root-14
