Answer:
[tex]\boxed{\bold{4x^2-12x+9}}[/tex]
Explanation:
Apply foil method [tex]\bold{\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd: \ a=2x,\:b=-3,\:c=2x,\:d=-3}[/tex]
[tex]\bold{2x\cdot \:2x+2x\left(-3\right)+\left(-3\right)\cdot \:2x+\left(-3\right)\left(-3\right)}[/tex]
Apply minus - plus rules
[tex]\bold{+\left(-a\right)=-a,\:\:\left(-a\right)\left(-b\right)=ab}[/tex]
[tex]\bold{2\cdot \:2xx-2\cdot \:3x-3\cdot \:2x+3\cdot \:3}[/tex]
Simplify
[tex]\bold{4x^2-12x+9}[/tex]
