By the end of the summer, sarah will earn $420 doing yard work. if she deposits this amount in a savings account paying 3.5% simple annual interest, what will her balance be at the end of 5 years?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
