Answer

(x-4), (x+1), (3x-5) Explanation 1. Test potential roots using synthetic division Use synthetic division to test each factor. Start with (x-4), (x+1), (3x-5), etc. 2. Perform synthetic division for (x-4) Divide 3x^4 - 14x^3 - 3x^2 + 54x - 40 by (x-4). The remainder is zero, so (x-4) is a factor. 3. Perform synthetic division for (x+1) Divide the quotient from Step2 by (x+1). The remainder is zero, so (x+1) is a factor. 4. Perform synthetic division for (3x-5) Divide the quotient from Step3 by (3x-5). The remainder is zero, so (3x-5) is a factor.

Explanation

1. Test potential roots using synthetic division<br /> Use synthetic division to test each factor. Start with $(x-4)$, $(x+1)$, $(3x-5)$, etc.<br />2. Perform synthetic division for $(x-4)$<br /> Divide $3x^4 - 14x^3 - 3x^2 + 54x - 40$ by $(x-4)$. The remainder is zero, so $(x-4)$ is a factor.<br />3. Perform synthetic division for $(x+1)$<br /> Divide the quotient from Step2 by $(x+1)$. The remainder is zero, so $(x+1)$ is a factor.<br />4. Perform synthetic division for $(3x-5)$<br /> Divide the quotient from Step3 by $(3x-5)$. The remainder is zero, so $(3x-5)$ is a factor.
