Question

Somebody plz help me solve!!

Answer 1

Answer:

C)  x = 3

Step-by-step explanation:

factor out a 2 to get:

2(x² - 6x + 9) = 0

(x-3)² = 0

x = 3

Answer 2

Answer and Step-by-step explanation:

First, to find the zeros of the function, we can take out a common factor from the equation, and then factor.

The equation has a common factor of 2 (so distribute of the 2 from all of the numbers).

2($x^2 - 6x + 9$)

Now, we factor. Find two numbers that multiplies to $9x^2$ and adds up to -6x.

-3x and -3x.

Now, we substitute these two for -6x.

$2(x^2 - 3x-3x+9)$

Factor.

$2(x - 3)(x-3)$

Finally, we set all of the values to 0 and solve for x.

2 ≠ 0

x - 3 = 0    x = 3

x - 3 = 0    x = 3

That means the answer is C. x = 3

(Not shown, but the multiplicity of this x value is 2, because there are two

x = 3)
