You can put this solution on YOUR website!
2x^2 + 8x - 25 = 0
this will not factor, no integer solutions; you have to use the quadratic formula:
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
In this equation, a=2; b=8; c=-25
x+=+%28-8+%2B-+sqrt%28+8%5E2-4%2A2%2A-25+%29%29%2F%282%2A2%29+
:
x+=+%28-8+%2B-+sqrt%28+64+%2B+200+%29%29%2F4+
:
x+=+%28-8+%2B-+sqrt%28+264+%29%29%2F4+
:
x+=+%28-8+%2B-+16.248%29%2F4+
Two solutions
x+=+%28-8+%2B+16.248%29%2F4+
x+=+8.248%2F4+
x = 2.062
and
x+=+%28-8+-+16.248%29%2F4+
x+=+%28-24.248%29%2F4+
x = -6.062
