Question

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

Answer 1

x= -2/5 and x= 3

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.
