Solve |{:(x^(2)-1,,x^(2)+2x+1,,2x^(2)+3x+1),(2x^(2)+x-1,,2x^(2)+5x-3,,4x^(2)+4x-3),(6x^(2)-x-2,,6x^(2)-7x+2,,12x^(2)-5x-2):}| =0

Suppose x^(2)-x +1 is factor of 2x^(6) - x^(5) + ax^(4) + x^(3)+bx^(2)-4x-3 . Find a-4b .

x^(3)-4x^(2)-3x+5;x-3

x ^ (3) + 5x ^ (2) -2x-24, x ^ (3) -4x ^ (2) + x + 6

The equation 4(5x^(2)-7x+2)=5(4x^(2)-6x+3) is
