5 ejercicios de factor comun resueltos?

1. ax + bx + ay + by = x(a + b)y(a + b) = (x + y)(a + b)

2.

(3x + 2y)² - (3x - 7y)² = (3x + 2y + 3x - 7y)(3x + 2y + 3x - 7y) = (6x - 5y)9y

3.

M(x) = ax + 7a + x + 7

M(x) = (ax + 7a) + (x + 7) = a(x + 7) + (x + 7)

M(x) = (x + 7)(a + 1)

4.

T(x ; y) = x⁸y² - x²y⁸

T(x ; y) = x²y²(x⁶ - y⁶)

T(x ; y) = x²y²(x³ - y³)(x³ + y³)

T(x ; y) = x²y²(x - y)(x² + xy + y²)(x + y)(x² - xy + y²)

5.

A = m²xy + mny² + mnx² + n²xy

A = (m²xy + mny²) + (mnx² + n²xy)

my(mx + ny) + nx(mx + ny)

A = (mx + ny)(my + nx)
