Question

using long division method show that 2x-3 is a factor of -6x²+8x³+5x-21​

Answer 1

Step-by-step explanation:

4x^4 + 8x^3 - (4x^4 + 6x^3) | 2x^3, R: 2x^3

2x^3 + 5x^2 - (2x^3 + 3x^2) | x^2 , R: 2x^2

2x^2 + x - (2x^2 + 3x) | x, R: -2x

-2x - 3 - (-2x - 3) | -1

Remainder: 0

End result: 2x^3 + x^2 + x - 1
