zeroes are 2+√3 & 2-√3
sum of the zeroes = 2+√3+2-√3 = 4
product of the zeroes = (2+√3)(2-√3) = 4-3= 1
p(x)= k[x²-(sum of the zeroes)x+ product of the zeroes]
p(x) = k(x²- 4x+1)
k=1
p(x) = x² - 4x + 1
sum of the zeroes = 2+√3+2-√3 = 4
product of the zeroes = (2+√3)(2-√3) = 4-3= 1
p(x)= k[x²-(sum of the zeroes)x+ product of the zeroes]
p(x) = k(x²- 4x+1)
k=1
p(x) = x² - 4x + 1
thanks
no problem
