x^4+6x^3-3x^2+24x-28 = ( x ^2 + 6x -7)(x^2+4) (you will get carry of the climate via assuming x^4+6x^3-3x^2+24x-28=(x^2+bx+c)(x^2+dx+d... and equate the coefficients the place you have 4 equations and four unknowns) zeros implies looking x for which f(x)=0, ( x ^2 + 6x -7)(x^2+4)=0 =>x=-7/a million/ ±2i so the complicated zeros are ±2i

Verified answer
-3X³-6X²+24X
Factor out the common factor:
-3X (X² + 2X - 8)
Factor what remains in parentheses:
-3X (X + 4) (X - 2)
x^4+6x^3-3x^2+24x-28 = ( x ^2 + 6x -7)(x^2+4) (you will get carry of the climate via assuming x^4+6x^3-3x^2+24x-28=(x^2+bx+c)(x^2+dx+d... and equate the coefficients the place you have 4 equations and four unknowns) zeros implies looking x for which f(x)=0, ( x ^2 + 6x -7)(x^2+4)=0 =>x=-7/a million/ ±2i so the complicated zeros are ±2i
