P(x)=3x2- 8x + 2K + 1 find the zeroes and value of K(teacher)
The polynomial has two zeroes: x1 and x2.
x2 = 7 * x1
by viet formulas we have:
x1 + x2 = - b/a
x1 + x2 = c/a
a = 3
b = -8
c = 2K + 1
Do you get it? ...

Need help with a riddle(parvez)
:D let a=b
a^2=ab
a^2-b^2=ab-b^2
(a+b)(a-b)=b(a-b)
a+b=b :shock:
let a=11,b=2
11+2=2
12+1=2
:P ...
