Identify the function for which you need to find the derivative: \( y = x^2 e^{3x^2 + 5x} \).
Recognize that this is a product of two functions: \( u(x) = x^2 \) and \( v(x) = e^{3x^2 + 5x} \). Use the product rule for differentiation, which states that \( (uv)' = u'v + uv' \).
Differentiate \( u(x) = x^2 \) to get \( u'(x) = 2x \).
Differentiate \( v(x) = e^{3x^2 + 5x} \) using the chain rule. First, differentiate the exponent \( 3x^2 + 5x \) to get \( 6x + 5 \), then multiply by the original function \( e^{3x^2 + 5x} \). Thus, \( v'(x) = (6x + 5)e^{3x^2 + 5x} \).
Apply the product rule: \( y' = u'v + uv' = 2x e^{3x^2 + 5x} + x^2 (6x + 5)e^{3x^2 + 5x} \). Simplify the expression to get the final derivative.
