Best ResponseYou've already chosen the best response.0Oh right. So have you heard of completing the square?

Best ResponseYou've already chosen the best response.0It's a way to solve the trinomial like you have above. I'll show you the steps. \[3x^2+6x=8\] The first step is to move the constant (8) on the other side but that is already done. What you have to do now is to take half the coefficient of x and add it to both sides. Can you do that?

Best ResponseYou've already chosen the best response.0Nah this is actually pretty hard.. but very useful when you learn it. In the term 6x, what is the coefficient of x (the number before x essentially).

Best ResponseYou've already chosen the best response.2the easiest thing to do is rewrite the equation as \[3x^2 + 6x  8 = 0\] then use the general quadratic formula for a quadratic \[ax^2 + bx  c = 0\] the formula is \[x = \frac{b \pm \sqrt{b^2  4ac}}{2a}\] your question has a = 3, b  6 and c = 8 substitute the values and calculate the answers

Best ResponseYou've already chosen the best response.0or you could do that.. I like completing the square. if you learn it it's much quicker than substituting values into the formula.

Best ResponseYou've already chosen the best response.0do what @campbell_st said use \[x = \frac{b \pm \sqrt{b^2  4ac}}{2a}\] with \[a=3,b=6,c=8\] that is all compute carefully

Best ResponseYou've already chosen the best response.0Bob and Susie wash cars for extra money over the summer. Bob's income is determined by f(x) = 6x + 13, where x is the number of hours. Susie's income is g(x) = 4x + 18. If Bob and Susie were to combine their efforts, their income would be h(x) = f(x) + g(x). Assume Bob works 3 hours. Create the function h(x) and indicate if Bob will make more money working alone or by teaming with Susie. A h(x) = 2x + 5, work alone B h(x) = 2x + 5, team with Susie C h(x) = 10x + 31, team with Susie D h(x) = 10x + 31, work alone
