16/2 Solve by completing the square.If the solutions are imaginary, write your answer together with the±sign. 3.x2 – 12x+ 27 = 0 Solutions:x=-3andx=-9 Use the table below to show your work. Step 1: Equation to completethe squareStep 2: Show work here tofind the c-value.Step 3: Show work here tofactor: (Don’t forget the signof the binomial) Step 4: Show work for solving for both roots. X²-12x=-27X²-12x+36=912/2=6(6)(6)=36(x-6)²=9(x-6)=3
4.n2– 2n– 18 = 6 Solutions:x=-26andx=24 Use the table below to show your work. Step 1: Equation to completethe squareStep 2: Show work here to
