A third degree polynomial equation (a cubic equation) is of the
form p(x) = c3x 3 + c2x
2 + c1x + c0, where x and
the four coefficients are integers for this exercise. Suppose the
values of the coefficients c0, c1,
c2, and c3have been loaded into
registers $t0, $t1, $t2, and $t3, respectively.
Suppose the value of x is in $t7.
Write the MIPS32 instructions that would evaluate this
polynomial, placing the result in $t9.
