PLEASE SEE THIS EXAMPLE WHICH IS SIMILAR TO YOUR PRESENT
PROBLEM AND SOLVE YOUR PROBLEM BY CHANGING VALUES OF a,b and c.
9x^2+3.2x+7.8=0...using formula for roots of a quadratic equation.ax^2+bx+c=0....
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ we get
x+=+%28-3.2+%2B-+sqrt%28+3.2%5E2-4%2A1.9%2A7.8+%29%29%2F%282%2A1.9%29+
x+=+%28-3.2+%2B-+sqrt%28+3.2%2A3.2-4%2A1.9%2A7.8+%29%29%2F%283.8%29+
x+=+%28-3.2+%2B-+sqrt%28-49%29%29%2F%283.8%29+
x+=+%28-3.2+%2B-+7i%29%2F%283.8%29+
x = -(1.6/1.9)+(7/3.8)i OR -(1.6/1.9)-(7/3.8)i
