Step-by-step explanation:

rest is easy and I think you should be able to do it

Answer 2

Answer:

$(3x {}^{4} - x {}^{2} + 6x - 7)(x {}^{2} - 3x + 4)$

$3x {}^{4}(x {}^{2} - 3x + 4) - x {}^{2} (x {}^{2} - 3x + 4) + 6x(x {}^{2} \\ - 3x + 4) + 4(x {}^{2} - 3x + 4)$

$3x {}^{6} - 9x {}^{5} + 12x {}^{4} - x {}^{4} - 3x {}^{3} - 4x {}^{2} + 6x {}^{3} - 18x {}^{2} + 24x - 7x {}^{2} + 21x - 28$

$3x {}^{6} - 9x {}^{5} + 11x {}^{4} + 3x {}^{3} - 29x {}^{2} + 55x - 28$

plzzzzzzzzz mark as brainliest.
