Best ResponseYou've already chosen the best response.2\[f(x) = x^35x^23x+15=0\]\[f(x) = x^2(x5) +3(x5) = 0\]\[f(x) = (x^2+3)(x5)=0\]\[x^2+3=0 \qquad x=~?\]\[x5=0 \qquad x=~?\]

Best ResponseYou've already chosen the best response.2\[x^2+3=0 \implies x^2=3\]\[x= \pm i\sqrt{3}\]Your answer choices are kind of weird.

Best ResponseYou've already chosen the best response.2Look at the choices. We know that \(7\) is definitely a zero. Divide the thing by \(x  7\). The remaining is a quadratic polynomial that can be factored.

Best ResponseYou've already chosen the best response.2=__=.... VF. How would that work here? we have one root = \((x7)\) Then we'd find \(\alpha +\beta \) and \(\alpha\beta\) ?
