5 ejercicios de factor comun resueltos

Answer 1

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)

Ojala te haya ayudado :D. Saluditos ;)
