Starting from scratch, it's possible to find the roots:
<span>4x^2=x^3+2x should be rearranged in descending order by powers of x:
x^3 - 4x^2 + 2x = 0. Factoring out x: </span>x(x^2 - 4x + 2) = 0
Clearly, one root is 0. We must now find the roots of (x^2 - 4x + 2):
Here we could learn a lot by graphing. The graph of y = x^2 - 4x + 2 never touches the x-axis, which tells us that (x^2 - 4x + 2) = 0 has no real roots other than x=0. You could also apply the quadratic formula here; if you do, you'll find that the discriminant is negative, meaning that you have two complex, unequal roots.
Answer:
No Solution.
Step-by-step explanation:
y=-3x+2
y=-3x-7
------------
-3x+2=-3x-7
-3x-(-3x)+2=-7
-3x+3x+2=-7
2=-7
no solution
Answer:
Yes
Step-by-step explanation:
because if you add that and then you subtract that you get that answer
