Question

Di faktorin nyari himpunan bantuin dong yang ada di gambar ini :)

Answer 1

A) 2x² - 5x + 3 > 0
(2x - 3)(x - 1) > 0
x = 3/2    x = 1

b) 2x² - x - 3 =< 0
(2x - 3)(x + 1) = 0
x = 3/2  x = -1

c) 3x² - x - 2 < 0
(3x + 2)(x - 1) = 0
x = - 2/3    x = 1

d) x² + 3x - 4 >= 0
(x - 1)(x + 4) = 0
x = 1  x = -4
