Question

find a quadratic polynomial whose zeroes are +root 15 and -root15

Answer 1

the quadratic polynomial whose zeroes are -: root 15 and -root15 is ------------->

x2 - 15

Answer 2

Answer:

x^2+-15

Step-by-step explanation:

k{x^2-x(alpha+beta)+alpha×beta}

So

k{x^2-x[√15+(-√15)]+√15×(-√15)}

k{x^2-x(0)+(-15)}

k{x^2-15}

Let k be 1

Therefore required polynomial is x^2-15
