Find all the zeros of f(x)=4x^3+24x^2+24x+20

Four solutions were found :

x = 7

x = 1

x =(-4-√12)/2=-2-√ 3 = -3.732

x =(-4+√12)/2=-2+√ 3 = -0.268

Step by step solution :

Step 1 :

Equation at the end of step 1 :

x4)-(4•(x3)))-(23•3x2))+20x)+7 = 0

Step 2 :

Equation at the end of step 2 :

x4) - 22x3) - (23•3x2)) + 20x) + 7 = 0

Step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
