Question

Find the value of x²-5x+3 if x = 15- √ 2

(please find the value or I'm gonna commit arson)



​

Answer 1

-43.73

Explanation:

15- sqrt2= 13.59

so x^2= 27.17

5x=67.9

27.17-67.9=-40.73

-40.73+3= -43.73

(success not guranteed)

Answer 2

(15 - √2)² - 5(15 - √2) + 3 =

225 - 30√2 + 2 - 75 + 5√2 + 3 =

152 - 25√2
