Question

a forma fatorada (1/4+7y)²

Answer 1

Resposta:

49y² + 7/2y + 1/16

Explicação passo-a-passo:

(1/4+7y)² = (1/4+7y).(1/4+7y)

(1/4+7y)² = 1/16 + 7/4y +7/4y + 49y²

(1/4+7y)² = 49y² + 2(7/4y) + 1/16

(1/4+7y)² = 49y² + 7/2y + 1/16

Answer 2

$( \frac{1}{4} + 7y) {}^{2} \\ ( \frac{1}{4} ) {}^{2} + 2 \: . \: \frac{1}{4} \: . \: 7y + (7y) {}^{2} \\ \boxed{\boxed{\boxed{ \frac{1}{16} + \frac{7}{2}y + 49y {}^{2} }}}$
