Question

Вынесите общий множитель за скобки
42a^2+16a
8x^4-24x^2
12a^5-18a^7
36a^4b-12ab^4
-11x^2y^2+22xy
-12a^3b^3+6ab

Answer 1

42а^2+16a= 2a(21a+8)

8x^4-24x^2 = 8x^2(x^2-3)

12a^5-18a^7= 6a^5(2-3a^2)

36a^4b-12ab^4= 12ab(3a^3-b^3)

-11x^2y^2+22xy= -11xy(xy-2)

-12a^3b^3+6ab=-6ab(2a^2b^2-1)

Answer 2

$1)42a {}^{2} + 16a \\ 2a \times (21a + 8) \\ \\ 2)8x {}^{4} - 24x {}^{2} \\ 8x {}^{2} \times (x {}^{2} - 3) \\ \\ 3)12a {}^{5} - 18a {}^{7} \\ 6a {}^{5} \times (2 - 3a {}^{2} ) \\ \\ 4)36a {}^{4} b - 12ab {}^{4 } \\ 12ab \times (3a {}^{3} - b {}^{3} ) \\ \\ 5) - 11x {}^{2} y {}^{2} + 22xy \\ - 11xy \times (xy - 2) \\ \\ 6) - 12a {}^{3} b {}^{3} + 6ab \\ - 6ab \times (2a {}^{2} b {}^{2} - 1)$
