Aparabola has a focus of f(β11,5) and a directrix of x=β12. the point p(x, y) represents any point on the parabola, while d(β12,y) represents any point on the directrix. miguel was asked to use the distance formula to write an equation to represent this parabola. here is his work: step 1: fp=dp step 2: (xβ(β11))2+(yβ5)2ββββββββββββββββββ ββ=(xβ(β12))2+(yβy)2βββββββββββββββ βββββ step 3: x2+22x+121+y2β10y+25=x2+24x+144 step 4: y2β10y+2=2x step 5: 12y2β10y+1=x identify each incorrect step. select all answer choices that both state an incorrect step and explain why it is incorrect. if there is only one incorrect step, select "only" and the answer choice that states and explains the incorrect step.\ 1, step 3 is incorrect because he expanded the first binomial incorrectly. 2, step 5 is incorrect because a previous step is incorrect 3, step 2 is incorrect because he used the wrong signs for the coordinates of the focus. 4, step 3 is incorrect because a previous step is incorrect. 5, step 5 is incorrect because he divided incorrectly. 6, only 7, step 4 is incorrect because a previous step is incorrect.
