Question

(2x-3)² qual é a resposta??​

Answer 1

Resposta:

4x^2-12x+9

Explicação passo-a-passo:

(a-b)^2 = a^2-2ab+b^2

So, (2x-3)^2 = 4x^2-2(2x)(3)+9

= 4x^2-12x+9

Answer 2

$\Large\mathsf\displaystyle{}\left(2x - 3\right) ^{2} \\\\ \Large\mathsf\displaystyle{}\left(2x\right)^{2} - 2\cdot2x\cdot3 + {3}^{2} \\ \Large\mathsf\displaystyle{} {4x}^{2} - 2\cdot2x + {3}^{2} \\ \Large\mathsf\displaystyle{} {4x}^{2} - 12x + {3}^{2} \\ \Large\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ {4x}^{2} - 12x + 9 }}}\end{gathered} }$

$\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{{ \red{Bons}} \blue{\:Estudos}}}}\end{gathered} }$
