Explanation Approach: The procedure to solve an inequality is as follow, Convert the given inequality in a standard form, a x n + b x n − 1 + ⋅ ⋅ ⋅ + c > , < , ≥ , o r ≤ 0... ( 2 ) . Convert the inequality into equation by equating with 0 . Solve the equation and find the values of x . Locate the values on number line and form intervals on the basis of values. Decide the intervals which satisfy the given inequality. The standard form of quadratic equation is, a x 2 + b x + c = 0... ( 3 ) The quadratic formula is given by, x = − b ± b 2 − 4 a c 2 a ... ( 4 ) Calculation: The given inequality is, 2 k 2 − 7 k − 15 ≤ 0... ( 1 ) Convert the given inequality into equation. 2 k 2 − 7 k − 15 = 0 Compare the above equation with equation ( 3 ) . a = 2 b = − 7 And, c = − 15 Substitute 2 for a , ( − 7 ) for b and ( − 15 ) for in equation. Take positive sign in above equation. Take negative sign in above equation. Figure shows the points on number line
