Okay so here;s the steps! \[5(x3)^{^{2}} 6\] the you get 5(x3)(x3)6 then you get \[5(x ^{2} 3x3x+9)\] then multiply 5 \[(5x ^{2} 30x +45) 6\] the last step is 456 is 39 so your answer will be... \[5x ^{^{2}} 30x +39\]

another approach vertex (h, k) h = b/2 a and k = a(b/2 a)^2 + c a = 5 3 = b/2*5 so b =30 (b/2a)^2 =(30/10)^2 = 9 6 = 5(9)+ c so c = 45  6 = 39 5 x^2 30 x + 39
