Question

1)The roots of a quadratic equation are 5 and - 2 then write the equation for it.​

Answer 1

Step-by-step explanation:

the equation is x^2-7x-10=0

Answer 2

Answer:

The roots of a quadratic equation are 5 and - 2 is x²-3x-10=0

Step-by-step explanation:

Given that:-

The roots of a quadratic equation are 5 and - 2

Let α=5 and β=-2

The quadratic equation whose roots are α and β is x²-(α+β)x+αβ=0

=>x²-[5+(-2)]x+(5)(-2)=0

=>x²-(5-2)x+(-10)=0

=>x²-3x-10=0

The roots of a quadratic equation are 5 and - 2 is x²-3x-10=0
