What does x equal 397x20142xSolution397 x2 142x multiplyin

What does x equal?

397=x²/(0.14-2x)

.397 = x^2 / (.14-2x)

multiplying both sides by (.14-2x)

we get

.05558 - .795x = x^2

we get a quadratic equation

x^2 + .795x -.05558 = 0

solving the quadratic by applying quadratic formula

x = { -b+- sqrt(b^2-4ac) } / 2a

we get two values of x

x1 = .0646

x2 = .8596
