The polynomial function q(x)=2x^4-9x^3-12x^2+29x+30

B (2x+3)(x-5)(x-2)(x+1)

Step-by-step explanation:

STEP 1:Equation at the end of step 1

2•(x4))-(9•(x3)))-(22•3x2))+29x)+30

step 2 Equation at the end of step 2:

2•(x4))-32x3)-(22•3x2))+29x)+30

step 3 Equation at the end of step 3:

(((2x4 -  32x3) -  (22•3x2)) +  29x) +  30
