Which are steps the could be used to slove 0=9(x2+6x)-18 by completing the square
Elis [28]

Answer:

(x+3)²-11=0

Step-by-step explanation:

0=9(x2+6x)-18

0= 9x² +54x-18

0= 9( x²+6x-2)    taking 9 common

0= x² +6x-2 (breaking the mid term to find the second element of the square

0 = (x)² +2(x)(3) +(3)² -2 -9 adding and subtracting the second element

0= (x+3)² -11 summing up
