Question

two zeros of the quadratic polynomial 2 x square - 7 x + 4 are alpha and beta find the values of Alpha by beta + beta by Alpha​

Answer 1

Answer:

If the two zeroes of the polynomial 2x²-7x + 4 = 0 are alpa and beta .

To prove :

alpa/beta + beta / alpa

Proof :

alpa + beta = -b/a

= -(-7)/2

= 7/2

alpa(beta) = c/a

= 4/2

= 2

Alpa/beta + beta / Alpa

Alpa + beta/ Alpa(Beta)

7/2 /2

7/2(1/2)

14/2

7
