Question

1) fatore as seguintes expressões algébricas;
a)3ax + ay + 3bx + by=
b)x²- 16y²=
c)a² - 1/4=

Answer 1

3ax + ay + 3bx + by
a(3x + y) + b(3x + y)
(a + b)(3x + y)

=======================

x² - 16y²
(x + 4y)(x - 4y)

=======================

a² - 1/4
a² = 1/4
a = raiz de 1/4
a = 1/2
(a + 1/2)(a - 1/2)
