Question

el desarrollo del cuadrado (4t-3h)^2 es:

Answer 1

$binomio \: al \: cuadrado = {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} \\ binomio \: al \: cuadrado = {(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2} \\ \\ {(4t - 3h)}^{2} = {(4t)}^{2} - 2(4t)(3h) + {(3h)}^{2} \\ {(4t - 3h)}^{2} = 16 {t}^{2} - 24th + 9 {h}^{2}$
