4x%5E2-5x%2B2%22%22=%22%22%220%22

a=4, b=-5, c=2

x%22%22=%22%22%28-b+%2B-+sqrt%28+b%5E2-4ac+%29%29%2F%282a%29+

x%22%22=%22%22%28-%28-5%29+%2B-+sqrt%28%28-5%29%5E2-4%284%29%282%29+%29%29%2F%282%284%29%29+

x%22%22=%22%22%285+%2B-+sqrt%2825-32%29%29%2F8+

x%22%22=%22%22%285+%2B-+sqrt%28-7%29%29%2F8+

x%22%22=%22%22%285+%2B-+i%2Asqrt%287%29%29%2F8+

%285+%2B+i%2Asqrt%287%29%29%2F8+, %285+-+i%2Asqrt%287%29%29%2F8+

or if you like you can write them this way:

5%2F8+%2B+expr%28sqrt%287%29%2F8%29i+, 5%2F8+-+expr%28sqrt%287%29%2F8%29i+
