Hey can you me posted picture of question

The solutions are -1 and 2/5

Explanation:
The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
5x² + 3x - 2 = 0
By comparison:
a = 5
b = 3
c = -2

Now, to get the roots (solutions) of the equation, we will need to use the quadratic formula shown in the attached image

Substituting in the equation, we would find that:
either x = -1
or x = 2/5

Hope this helps :)
