What is the value of x³ + y² + x²y³ - (x + y), when x = 4 and y = - 3

x³ + y² + x²y³ - (x + y), when x = 4 and y = - 3

= 4³ + (-3)² + (4)²(-3)³ - [4 + (-3)] {substituted 4 for x and -3 for y}

= 64 + 9 + 16(-27) - (4 - 3) {simplified}

= 64 + 9 - 432 - 1 {multiplied}

=

= 4³ + (-3)² + (4)²(-3)³ - [4 + (-3)] {substituted 4 for x and -3 for y}

= 64 + 9 + 16(-27) - (4 - 3) {simplified}

= 64 + 9 - 432 - 1 {multiplied}

=
