Factor completely x^2-48

fredd [130]

Answer: $(x-7)(x+7)$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below;

- Make the equation equal to zero:

$x^{2}-49=0$

-Add 49 at both sides:

$x^{2}=49$

- Now, you must take the square root of both sides of the equation, then you obtain the following roots:

$x=\sqrt{49}\\x_1=7\\x_2=-7$

- Then you have:

$x^{2}-49=$ $(x-7)(x+7)$

Y=3x+1 and y+5=-3(x-2)

In-s [12.5K]

Answer:

X = -2/3 ; Y = -1

Step-by-step explanation:

Y=3x+1-------------------(eqn1)

Y+5= -3(x-2)

Y+5= -3x + 2

Y= -3x+2-5

Y= -3x-3----------------(eqn2)

Equating (eqn1) =(eqn2)

3x + 1 = -3x - 3

3x + 3x = -1-3

6x = -4

X = -4/ 6 = -2/3

From eqn 1 Y = 3( -2/3) + 1 = -2 + 1 = -1

X = -2/3 ; Y = -1
