Determine the values of x for the following inequality x2 – 3x – 28 < 0? – 4 < x < 7 4 < x < -7 - 4 < x < -7 4 < x < 7 None of these
Question
Solution 1
To solve the inequality x^2 - 3x - 28 < 0, we first need to factor the quadratic expression on the left side of the inequality.
The quadratic x^2 - 3x - 28 factors to (x - 7)(x + 4).
Setting each factor equal to zero gives the potential turning points x = 7 and x = -4.
