Question

If alpha and beta are the zeroes of x 2 - 2x – 7 then form a quadratic polynomial whose zeroes are 2alpha and 2beta

no spaming pls

Answer 1

Answer:

2X²-4x-14 is the answer

Step-by-step explanation:

given alpha and beta are the zeros of the equation x²-2x-7.

we need to get a equation whose zeros are 2 alpha and 2 beta.

to get that, we should multiply the entire equation with 2,

which implies

2(x²-2x-7)=0

2x²-4x-14=0

so 2x²-4x-14=0 is the answer
