Question

Solve this expression 5x^2-13x-6

Answer 1

Answer:

x= -2/5 and x= 3

Step-by-step explanation:

Given equation is,

5x^2 -  13x -  6  = 0

Or, 5x^2 -  15x + 2x -  6  = 0 ( using middle term method)

Or, 5x( x- 3) + 2 (x-3) = 0

Or, (x-3) (5x+2) = 0

Now, x will have 2 answers because it's degree is 2. Total number of values depends on the power of variable.

So, x= 3 or, 5x = -2

             Or, x= -2/5

So, the answer is  x= -2/5 and x= 3.
