Question

if 3 and -10 are the roots of equation then fine quadratic equation
​

Answer 1

Answer:

x^2 + 7x - 30 = 0

Step-by-step explanation:

Let a (alpha) and b (beta) be the roots of the required quadratic equation.

a = 3 and b = -10

(a + b) = -7

ab = -30

The required quadratic equation is,

x^2 - (a + b)x +ab = 0

x^2 - (-7)x + (-30) = 0

x^2 + 7x - 30 = 0.

I hope this helps! Please comment if there are any mistakes in the solution!!
