Question

Helpppppppp. This is hard to me
if x^2 + x - 3 = 0
what is the value of x^3 + 4x^2 + 2014 ?

Answer 1

First I recommend solving x^2 + x - 3 = 0 for x

You would use the quadratic formula to solve for x

Answer 2

Once you have your solutions, plug them into x^3 + 4x^2 + 2014 one at a time

Answer 3

is there an alternative way without solve for x ?

Answer 4

i make that equation be
x^2 + x - 3 = 0
times by x on both sides, i get
x^3 + x^2 - 3x = 0
but i dont know how to make this be like equation x^3 + 4x^2 + 2014 ?
