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 .

Solve √3-5x=√x+2 what is the value of x?

FromTheMoon [43]

Answer:

x= $\frac{1}{6}$

Step-by-step explanation:

We have given,

$\sqrt{3-5x} =\sqrt{x+2}$

We need to solve for x.

$\sqrt{3-5x} =\sqrt{x+2}$

Squaring both sides, we get:

3-5x = x + 2

or 3 - 2 = x + 5x

or 1 = 6x

or x = $\frac{1}{6}$

Hence we got x= $\frac{1}{6}$
