Question

Evaluate the polynomial for x=-4

Answer 1

The answer is

1225

Explanation:

4x² + 5 - 6x³ + 3x⁴ - x

x = - 4

Substitute the value of x into the expression

That's

4(-4)² + 5 - 6(-4)³ + 3( 4 )⁴ - - 4

Simplify

4(16) + 5 - 6( -64) + 3( 256) + 4

64 + 5 + 384 + 768 + 4

We have the final answer as

1225
