Answer :
[tex]2( x^{2} -4.5x)+9=0[/tex]
[tex]2[(x-2.25) ^{2}-5.0625]+9=0 [/tex]
[tex]2(x-2.25) ^{2}-10.125+9=0 [/tex]
[tex]2(x-2.25) ^{2}-1.125=0 [/tex]
[tex](x-2.25) ^{2}=0.5625 [/tex]
[tex]x-2.25= \sqrt{0.5625} [/tex]
[tex]x-2.25=0.75[/tex]
[tex]x-2.25=-0.75[/tex]
[tex]x=3[/tex] or [tex]x=1.5[/tex]
Hope this helped
