Matematica Flashcards
1
Q
x^3 + x^2
A
x^3 + x^2 = x^2(x + 1)
2
Q
Factoriza: 2x^4 + 4x^2
A
2x^4 + 4x^2 = 2x^2(x^2 + 2)
3
Q
Factoriza: x^2 - 4
A
x^2 - 4 = (x + 2)(x - 2)
x = -2 y x = 2
4
Q
Factoriza: x^4 - 16
A
x^4 - 16 = (x^2 + 4)(x^2 - 4)
x^4 - 16 = (x^2 + 4)(x^2 - 4) = (x^2 + 4)(x + 2)(x - 2)
x = -2 y x = 2
5
Q
Factoriza: x^2 + 6x + 9
A
x^2 + 6x + 9 = (x + 3)^2
x = -3
