(carilah HP pertidaksamaan)

Answer 1

=2x^+3x+2x+3 >1 =2x^+5x+3 >1 =x^+5x+6 >1 =(x+6)(x+1) >1 x=-6 x=-1 >1 sorry y klo salah

Answer 2

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

2x + 1 > 0 \/ x + 2 = 0
2x > -1 \/ x = - 2
x > -1/2 \/ x = -2

Himpunan Penyelesaian: {-1/2 , -2}
