Evaluate − 5 x 2 − y 3 when x = − 4 and y = − 5

45

Step-by-step explanation:

-5x^2 - y^3 when x = -4 and x = -5

~Substitute

-5(-4)^2 - (-5)^3

~Simplify

-5(16) - (-125)

-80 + 125

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
