Question

3.5 and 3 write a quadratic equation with each pair of values as roots

Answer 1

Hello from MrBillDoesMath!

Answer: x^2 - 6.5x + 10.5 = 0

Discussion:

If the roots are 3 and 3.5, then the quadratic equation is

(x -3 ) ( x - 3.5) = 0

or

x * (x - 3.5) - 3 (x - 3.5) = 0

or

X^2 - 3.5X - 3X + 3(3.5) = 0

or

x^2 - 6.5x + 10.5 = 0

Thank you,

MrB
