For which values of x does this equation stands true: 3x^{2} – 7x – 6 < 0
For which values of x does this equation stands true x^{2} – 14x – 15 > 0 ?
At x = 0 inequality is not satisfied.
Thus x = –1 and x = 15 are the roots of the quadratic equation.
Thus, option (d) is correct.
For which values of x does this equation stands true x^{2}  4x < 5 ?
At x = 0 inequality is satisfied, option(b) is rejected. At x = 2, inequality is satisfied, option (c) is rejected.
At x = 5, LHS = RHS.
At x = –1, LHS = RHS.
Thus, option (a) is correct.
For which values of x does this equation stands true x – 6 > x^{2} – 5x + 9 ?
Thus, option (b) is correct.
For which values of x does this equation stands true x^{2} – 2x < x ?
Thus, option (a) is correct.
For which values of x does this equation stands true x^{2} –7x + 12 < x – 4 ?
Thus, Option (e) is correct.
For which values of x does this equation stands true x^{2} – 2x < x ?
Thus, option (d) is correct.
For which values of x does this equation stands true 2 – x – x^{2} ≥ 0 ?
At x = 0, inequality is satisfied.
Thus, options, (c) and (d) are rejected.
At x = 1, inequality is satisfied
Hence, we choose option (b).
For which values of x does this equation stands true x^{2} – 5x – 3 – x < 2 ?
At x = 0, inequality is satisfied, option (a) rejected. At x = 10, inequality is not satisfied, option (c) rejected.
At x = –5, LHS = RHS.
Also at x = 5, inequality is satisfied and at x = 6, inequality is not satisfied. Thus, option (c) is correct.
For which values of x does this equation stands true x^{2} – 3x + x – 2 < 0 ?
The options need to be converted to approximate values before you judge the answer. At x = 0, inequality is satisfied.
Thus, option (b) and (d) are rejected.
Option (a) is correct.
