what would b the roots for this equation??

Question

X^2 - 5/2x -6

Answer 1

If you mean x² - (5/2)x - 6 = 0, then the problem can be solved as follows:

 

Multiply both sides by 2 to clear fractions (multiplying an equation by a nonzero constant has no effect on the roots).

 

2x² - 5x - 12 = 0

 

(2x + 3)(x - 4) = 0

 

So, 2x + 3 = 0 or x - 4 = 0

 

x = -3/2, or x = 4
