1.5x - (x + 3) = 51.5x - x - 3 = 50.5x - 3 = 50.5x = 8x = 16
x^2 + 2x + 11 = 0This quadratic equation has no real roots since the discriminant (b^2 - 4ac) is negative.
-x^2 + 2x - 15 < 0The solution to this inequality is x < 3 or x > 5.
x • (3 - x) > 0The solution to this inequality is x < 0 or x > 3.
1.5x - (x + 3) = 5
1.5x - x - 3 = 5
0.5x - 3 = 5
0.5x = 8
x = 16
x^2 + 2x + 11 = 0
This quadratic equation has no real roots since the discriminant (b^2 - 4ac) is negative.
-x^2 + 2x - 15 < 0
The solution to this inequality is x < 3 or x > 5.
x • (3 - x) > 0
The solution to this inequality is x < 0 or x > 3.
