We are given the following expression and want to expand it and simplify it.

$(x+9)(x+2)$

Use the FOIL method for expanding

$=x^2+9x+2x+(9\times2)$

Simplify

$=x^2+11x+18$

Let me know if you have any questions or need clarifications, thanks!

Let g be the function given by g(x)=x^2*e^(kx) , where k is a constant. For what value of k does g have a critical point at x=2/

ArbitrLikvidat [17]

G `( x ) = $2x * e^{kx} + k x^{2} *e^{kx} = \\ = xe^{kx}(2 + kx )$
2 + k x = 0
k x = -2
k = -2: x = - 2 : 2/3 = - 2 * 3/2
k = - 3
Answer: for k= - 3, the function g ( x ) have a critical point at x = 2/3.
