Properties of eq2 roots

If p and q are the zeroes of the quadratic polynomial f(x) = 2x2 - 7x + 3, find the value of p + q - pq.

Correct answer:

v =  2

Step-by-step explanation:

f(x) = 2x2  7x + 3 2x27x+3  2x27x+3=0  a=2;b=7;c=3 D=b24ac=72423=25 D>0  x1,2=2ab±D=47±25 x1,2=47±5 x1,2=1.75±1.25 x1=3 x2=0.5  p=x1=3 q=x2=0.5=21  v=p+qp q=3+0.53 0.5=2
