Question

Find a quadratic polynomial, the sum and product of whose zeroes are -3 and 5 respectively

Answer 1

Here is your answer

Sum of zeroes = -3
Product of zeroes = 5

so the quadratic equation is
$x {}^{2} - ( - 3)x + 5 = 0 \\ x {}^{2} + 3x + 5 = 0$
Hope it helps you

Answer 2

alpha+beta=-3
alpha×beta=5
x2+(alpha+beta) x+alpha×beta
=x2+(-3) x+5
=x2-3x+5=0

here x2 is x square
