Question

simplify (x square - 1 +2x) (x square - 1 - 2x)​

Answer 1

Answer:

We know that the general form of quadratic equation is ax

2

+bx+c=0.

The given equation is (x+2)

3

=2x(x

2

−1) can be simplified as follows:

(x+2)

3

=2x(x

2

−1)

⇒x

3

+2

3

+(3×x×2)(x+2)=2x

3

−2x(∵(a+b)

3

=a

3

+b

3

+3ab(a+b))

⇒x

3

+8+6x(x+2)=2x

3

−2x

⇒x

3

+8+6x

2

+12x=2x

3

−2x

⇒x

3

+8+6x

2

+12x−2x

3

+2x=0

⇒−x

3

+6x

2

+14x+8=0

Answer 2

Answer:

$x {}^{2}(re( - 1)a.q.s.u - 2) {}^{2}$

$x {}^{2}s {}^{2}q {}^{2}u {}^{2}a {}^{2}re( - 1) {}^{2} - 4x {}^{2} s.q.u.a.re( - 1) + 4x {}^{2}$

this two answer I have ok I hope this is a correct answer ok ARMY...
