Solve the polynomial. x^3 + 4x^3 - 11x - 30 = 0

The answer is approximately 2.21456

Step-by-step explanation:

1. You simplify your equation to:

5x^3-11x-30=0

2. Now you can use the Newton Raphson method to solve this problem.

The Newton Raphson method can be used by calculating x + 1 until its delta turns into something below 0.00001, and the x value is your answer.

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
