Best ResponseYou've already chosen the best response.1You can factor, but let's use the quadratic equation to solve this \[\Large 0 = 6x^2  10x  4\] \[\Large 6x^2  10x  4 = 0\] \[\Large x = \frac{b\pm\sqrt{b^24ac}}{2a}\] \[\Large x = \frac{(10)\pm\sqrt{(10)^24(6)(4)}}{2(6)}\] \[\Large x = \frac{10\pm\sqrt{100(96)}}{12}\] \[\Large x = \frac{10\pm\sqrt{196}}{12}\] \[\Large x = \frac{10+\sqrt{196}}{12} \ \text{or} \ x = \frac{10\sqrt{196}}{12}\] \[\Large x = \frac{10+14}{12} \ \text{or} \ x = \frac{1014}{12}\] \[\Large x = \frac{24}{12} \ \text{or} \ x = \frac{4}{12}\] \[\Large x = 2 \ \text{or} \ x = \frac{1}{3}\] So you are correct iloveboys, nice work

Best ResponseYou've already chosen the best response.1since the x intercepts are 2 and 2, we know that x = 2 and x = 2 are zeros So... x = 2 or x = 2 x + 2 = 0 or x  2 = 0 (x + 2)(x  2) = 0 x^2  4 = 0 Which is a difference of two squares since 4 is 2^2

Best ResponseYou've already chosen the best response.1Part 1: Solve each of the quadratic equations below and describe what the solution(s) represent to the graph of each. Show your work to receive full credit. •y = x2 + 3x + 2. •y = x2 + 2x + 1. Part 2: Using complete sentences, answer the following questions about the two quadratic equations above. •Do the two quadratic equations have anything in common? If so, what?. •What makes y = x2 + 3x + 2 different from y = x2 + 2x + 1?.

Best ResponseYou've already chosen the best response.1Part 1 y = x^2 + 3x + 2 0 = x^2 + 3x + 2 x^2 + 3x + 2 = 0 (x+2)(x+1) = 0 x+2=0 or x+1=0 x=2 or x=1 So the solutions to y = x^2 + 3x + 2 are x=2 or x=1  y = x^2 + 2x + 1 0 = x^2 + 2x + 1 x^2 + 2x + 1 = 0 (x+1)^2 = 0 x+1 = 0 x = 1 So the only solution to y = x^2 + 2x + 1 is x = 1

Best ResponseYou've already chosen the best response.1Part 2 Similarities: The two are similar in that they both are quadratic equations and graph parabolas. The two also open up in the same direction and have the same basic shape. The two quadratics are also factorable.  Differences: y = x^2 + 3x + 2 has 2 solutions or zeros y = x^2 + 2x + 1 has only 1 solution y = x^2 + 3x + 2 intersects the xaxis twice at 2 different spots y = x^2 + 2x + 1 only touches the xaxis at one spot only

Best ResponseYou've already chosen the best response.1Use the quadratic formula to solve for x \[\Large x = \frac{b\pm\sqrt{b^24ac}}{2a}\] \[\Large x = \frac{(2)\pm\sqrt{(2)^24(1)(24)}}{2(1)}\] \[\Large x = \frac{2\pm\sqrt{4(96)}}{2}\] \[\Large x = \frac{2\pm\sqrt{100}}{2}\] \[\Large x = \frac{2+\sqrt{100}}{2} \ \text{or} \ x = \frac{2\sqrt{100}}{2}\] \[\Large x = \frac{2+10}{2} \ \text{or} \ x = \frac{210}{2}\] \[\Large x = \frac{12}{2} \ \text{or} \ x = \frac{8}{2}\] \[\Large x = 6 \ \text{or} \ x = 4\] So the answer is choice A
