What is the quadratic equation that has roots of,-3 And 2/5

Answer: 5x² + 13x - 6 = 0

Step-by-step explanation:

Represent the roots with X i. e.

X = - 3; X = 2/5

Moving the values of X over the equator we have;

X + 3 = 0; 5X - 2 = 0

Equating both equations to zero we can obtain;

(X + 3) (5X - 2) = 0

Opening the brackets we get;

5x² - 2x + 15x - 6 = 0

The result of the above equation gives;

5x² + 13x - 6 = 0
