Question

(m+3)²=(m²)+2(m)+(3²)​

Answer 1

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\blue{\boxed{\boxed{\red{¡ʜ}\blue{ᴏ}\purple{ʟ}\orange{ᴀ!}}}}$

$\bf\green{\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: Resolvemos:}$

$\bf(m + 3 {)}^{2} = ( {m}^{2} ) + 2(m) + ( {3}^{2} )$

$\bf {m}^{2} + 6m + 9 = {m}^{2} + 2m + {3}^{2}$

$\bf6m + 9 = 2m + {3}^{2}$

$\bf6m + 9 = 2m + 9$

$\bf6m = 2m$

$\bf6m - 2m = 0$

$\bf4m = 0$

$\boxed{ \bf{m = 0}}$
