X to the third plus x minus 7 equals -3 square root of x - 1

Ugo [173]

Answer:

x ≈ 1.5004

Step-by-step explanation:

We suppose your equation is ...

$x^3+x-7=-3\sqrt{x-1}$

Squaring both sides and subtracting the right side gives ...

$x^6 +2x^4 -14x^3 +x^2 -23x +58 = 0$

This 6th-degree equation has two positive real roots, near x=1.5, and x=2. The root at x=2 is extraneous. The one near x=1.5 is irrational.

3x+2(1-2x)=0

3x+2-4x=0

-x+2=0

-x=-2

x=2

2x+y=1

2(2)+y=1

4+y=1

y=-3
