Respuesta :
(x-3)² = (x-3)(x-3) = x² -3x -3x +9 or x² ,- 6x + 9. answer C
Answer:
Therefore, c) x²- 6x. +9 .
Step-by-step explanation:
Given: (x - 3) ² = 0
To find: Write the quadratic equation in standard form.
Solution: We have given that (x - 3) ² = 0
By the (a- b) ²=a²+ b²- 2ab
Here a= x and b= 3
(x- 3) ²= x²+ 3²- 2* x * 3
(x- 3) ²= x²+9 - 6x.
Therefore, c) x²- 6x. +9 .
