Question 649992

if {{{x= -3}}}, the value of :

{{{3 ^2=(-3)^2=(-3)(-3)=9}}}

{{{(2x-3)^ 2=(2(3-5x) (2 + x)-3)^ 2=(-6-3)^ 2=(-9)^ 2=(-9)(-9)=81}}}

{{{(3-5x) (2 + x)=(3-5(-3)) (2 + (-3))=(3+15) (2 -3)=18(-1)=-18}}}

{{{3x^2 + 2 x +5=3(-3)^2 + 2 (-3) +5=3(9) -6 +5=27-6+5=32-6=26}}}

{{{(3x-10)^2=(3(-3)-10)^2=(-9-10)^2=(-19)^2=361}}}

{{{(1-2x)^3=(1-2(-3))^3=(1+3)^3=4^3=4*4*4=64}}}
