Write the factored form of this trinomial 9x^2+18x-7

Write the equation for the graph with the vertex (-6,2) and focus (-7.25,2) a. (y-2)^2 = -5(x+6) b. (y+6)^2 = -5(x-2) c. (x+6)^2 = -5(y+2) d. (y-6)^2 = 5(x+6)

Consider the linear model for a two-stage nested design with b nested in a as given below. yijk=\small \mu + \small \taui + \small \betaj(i) + \small \varepsilon(ij)k , for i=1,; j= ; k=1, assumption: \small \varepsilon(ij)k ~ iid n (0, \small \sigma2) ; \small \taui ~ iid n(0, \small \sigmat2 ); \tiny \sum_{j=1}^{b} \small \betaj(i) =0; \small \varepsilon(ij)k and \small \taui are independent. using only the given information, derive the least square estimator of \small \betaj(i) using the appropriate constraints (sum to zero constraints) and derive e(msb(a) ).
