X = - 63 /9
X = -7
Would u mind sending the figure..!please

Answer:
No, she's incorrect. You cannot split up something in parenthesis when it is being squared. By doing so she doesn't have a middle term. The correct equation is 25x^6 + 30x^3 + 9
Step-by-step explanation:
1. Square the first term.
(5x^3)^2 = 25x^6
2. Square the second term.
3^2 = 9
3. Multply the two terms together and multiply by two.
5x^3 × 3 = 15x^3
15x^3 × 2 = 30x^3
4. Add everything together.
25x^6 + 30x^3 + 9
I hope this helps!
