Question

de
termine o M.M.C dos monômios e polinômios :
a) 15x² e 20x³y

b) a²,ab² e a+b

c) 4x + 4 e 10x + 10

d) 8x + 8y e x² - y²

e) x² - 14x + 49 e 2x - 14

Answer 1

Respostas:

a)..... 15x² = 3.5.x²...........e.....20x³y = 4.5.x³.y

m.m.c. = 3.4.5.x³.y = 60.x³y

b).....a² = a².......ab² = a.b²......e....a+b = a+b

m.m.c = a².b².(a+b) = a²b².(a+b)

c) ...4x + 4 = 4.(x + 1).....e....10x + 10 = 2.5.(x + 1)

m.m.c = 4.5.(x + 1) = 20.(x + 1)

d)....8x + 8y = 8.(x + y)....e....x² - y² = (x + y).(x - y)

m.m.c. = 8.(x + y).(x - y)

e)....x² - 14x + 49 = (x - 7)²......e.....2x - 14 = 2.(x - 7)

m.m.c. = 2.(x - 7)²
