Let's solve the quadratic equation:
x^2+3x = 285
First we need to put the equation in the form:
ax^2 + bx + c = 0
For this, we set the equation to equal 0, and arrange the terms from the highest exponent to the lowest:
x^2+3x-285 = 0
We have:
a=1 b=3 c=-285
We can now apply the quadratic formula:
x = ( -b ± √(b²-4ac) ) / 2a
We find two solutions:
x=15.448451256678 or x=-18.448451256678
