Question

write the quadratic equation ,whose roots 2 and minus 1​

Answer 1

Step-by-step explanation:

Roots are - 1 and - 2

Sum of roots = - 1 - 2 = -3

Product of roots = (-1)(-2) = 2

Required equation is

x^2 - (sum of roots) x + Product of roots = 0

=> x^2 - (-3)x +2 = 0

=> x^2 +3x +2 = 0

Answer 2

Answer:

${x}^{2} - x - 2 = 0$

Step-by-step explanation:

x=-1, x=2

(x+1)(x-2)=0

${x}^{2} \: - x - 2 = 0$
