You can put this solution on YOUR website!
1) 5x^2 -13x+ 6=0 ( ^2 Used for Squared)
(5x -3)(x -2) = 0, x = 2, 3/5
Or
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%2813+%2B-+sqrt%28+49+%29%29%2F%2810%29+
x+=+%2813+%2B-+7%29%2F%2810%29+
x = 2, x = 6/10 = 3/5
.......
2x^2 +4x=3x
2x^2 + x = 0
x(2x - 1) = 0, x = 0 0r x = -1/2
0r
2x^2 + x + 0 = 0
x+=+%28-1+%2B-+sqrt%28+1%29%29%2F%284%29+
x+=+%28-1+%2B-+1%29%2F%284%29+
x = 0, x = -2/4 = -1/2
......
3x^2-5x=0
x(3x-5) = 0, x = 0, x = 5/3
0r
3x^2-5x + 0=0
x+=+%285+%2B-+5%29%29%2F%286%29+
x = 0, x = 10/6 = 5/3

I'll solve the first equation for you.
You can solve the other two using the same technique, or post each equation as a separate question and I'll solve all the equations for you.

5xx - 13x + 6 = 0
---
the above quadratic equation is in standard form, with a=5, b=-13 and c=6
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
5 -13 6
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic has two real roots at:
---
x = 2
x = 0.6
