Question

the roots of a quadratic equation are 5 and -2 then the equation is
a. x2 - 3x + 10=0
b. x2 - 3x - 10= 0
c. x2 + 3x - 10=0
d. x2 + 3x + 10=0 ​

Answer 1

Step-by-step explanation:

let a and b be roots.....

a +b = 3

ab = -10

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

x^2 -(3)x -10 = 0

So your answer is =>

x^2 -3x -10= 0

option (b) is correct✅
