You can put this solution on YOUR website!

if you have 2x%5E2-7x+, to find solutions (you have second degree function, so you will have two solutions) first make it equal to zero

2x%5E2-7x=0 ...factor out x

x%282x-7%29=0
solutions:
x%282x-7%29=0 will be true if => x=0 or %282x-7%29=0
so,the first solution is x=0
and if %282x-7%29=0 => 2x=7 => x=7%2F2=> x=3.5

so, the second solution is x=3.5
