Rearrange the following formula to make x the subject. y=4x-7

A particle P of mass 0.4 kg is moving under the action of a constant force F newtons. Initially the velocity of P is (6i – 27j) m s−1 and 4 s later the velocity of P is (−14i + 21j) m s−1 . Find, in terms of i and j, the acceleration of P.

For what values of x is 2x^2 - 11x - 6 > 0 ?
