Question

Expansion of 〖(x+2)〗^2 is ​

Answer 1

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Expand ${(x + 2)}^{2}$

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

${(x + 2)}^{2}$

$= {(x)}^{2} + {(2)}^{2} + 2 \times 2 \times x$

$= {x}^{2} + 4 + 4x$

$= {x}^{2} + 4x + 4$

$\star\:\:\:\bf\large\blue{Identity\:Used:-}$

${(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2}$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• ${(x + 2)}^{2} = {x}^{2} + 4x + 4$

Answer 2

Answer:

x^2 + 4x + 4

Step-by-step explanation:

Applying identity (a+b)^2 = a^2 +2*a*b +b^2
