Question

If does zeros of the polynomial of x square + px + q is doubled the zero of the polynomial x square - 5 x minus 3 then find p and q.

Answer 1

Step-by-step explanation:

Answer:

p = -5, q = -6

Step-by-step explanation:

2x²-5x-3 = 2x²-6x+x-3

              = 2x(x-3)+1(x-3)

              = (x-3)(2x+1)

Hence, the zeros of 2x²-5x-3 are -1/2 and 3.

Zeros of the polynomial x²+px+q  are double in value to -1/2 and 3,

Thus zeros are -1 and 6.

Now, quadratic expression with zeros -1 and 6 is given by

(x + 1)(x-6) = x²-5x-6. By comparison, p = -5 and q

= -6.

Answer 2

Answer:

the answer is -6
