Question

2. Solve (3x + 2x2 + 4x3 ) = (x - 4)​

Answer 1

Answer:

2x^3+ x^2 + x -2 =0

Step-by-step explanation:

(3x + 2x^2 + 4x^3 ) = (x - 4)​

3x + 2x^2 + 4x^3= x - 4

4x^3+ 2x^2 + 2x -4 = 0

2(2x^3+ x^2 + x -2)= 0

2x^3+ x^2 + x -2 =0

Answer 2

Answer:

x=10

Step-by-step explanation:

(3x+2×2+4×3)=(x-4)

3x+4+12=x-4

3x+16=x-4

3x-x=-4-16

2x=-20

x=20÷2

x=10
