Dy/dx when y=x^2e^5x

I believe the problem asks for the slope. This problem can be done by putting <span>y=x^2e^5x into slope intercept form. However, the issue is that there is the variable "e", which does not match the slope intercept formula, y=mx+b. Long explanation short, the slope is </span> $3e^5x^2$
