Question

From the euadratic equation if roots are 3 and -10

Answer 1

Answer:

Roots of the quadratic equation are 3 and 10

Then, (x−3)(x−10)=0

x(x−10)−3(x−10)=0

x

2

−10x−3x+30=0

∴x

2

−13x+30=0

This is the required quadratic equation

Answer 2

Answer:

Roots of the quadratic equation are 3 and 10

Then, (x−3)(x−10)=0

x(x−10)−3(x−10)=0

x2−10x−3x+30=0

∴x2−13x+30=0

This is the required quadratic equation.
