Answer:

x=-2,-4 is your answer

x²+6x+8=0

doing middle term factorization

x²+4x+2x+8=0

x(x+4)+2(x+4)=0

(x+4)(x+2)=0

either

x=-4

or

x=-2

Step-by-step explanation:

❁ \underline{ \underline{  \large{\tt{T \: O \:  \: F \: A \: C \: T \: O \: R \: I\: Z \: E \: }}}} :

  • \large{ \tt{ {x}^{2}  + 6x + 8}}

❁ \underline{ \underline{ \large { \tt{S \: O \: L \: U \: T \: I \: O \: N}} }} :

Firstly find two numbers which when multiplied results to 8 and when added,it results to 6. The two numbers must be 4 and 2.

⟶ \large{ \tt{ {x}^{2}  + (4 + 2)x + 8}}

⟶ \large{ \tt{  \underbrace{{x}^{2}  + 4x} +  \underbrace{2x + 8}}}

Now, Take common from first two terms :

⟶ \large {\tt{x(x + 4) + 2x + 8}}

Take common from last two terms :

⟶ \large{ \tt{x(x + 4) + 2(x + 4)}}

⟶ \large{ \tt{(x + 4)(x + 2)}}

⟿ \boxed{ \boxed{ \underline{ \text{Our \: Final \: Answer :  \boxed{ \bold{ \text{(x + 4)(x + 2)}}}}}}}

Hope I helped ! ツ

Have a wonderful day / night ! ♡

A line passes through the point (-6, -8) and has a slope of 3/2
garri49 [273]

Answer:

y=3/2(x) -1, or y = 1.5x - 1

Step-by-step explanation:

To write the equation in slope-intercept form, you have to determine the y-intercept for the line. Since you have the slope and at least one ordered pair, you can find this by substituting the points and slope into this formula:

y=mx+b.

For this particular line, you would write:

-8 = 3/2(-6)+b

-8 = -18/2 + b

-8 = -9 + b

add 9 to both sides to isolate the b

-1 = b.

Now that you have the answer for b (-1), you can write the equation as:

y=3/2(x) -1

Using perfect factors find the square root of 1764
Zolol [24]

The square root of 1764 using perfect factors is 42

<h3>How to determine the square root using perfect factors?</h3>

The number is given as:

1764

Rewrite as

x^2 = 1764

Express 1764 as the product of its factors

x^2 = 2 * 2 * 3 * 3  * 7 * 7

Express as squares

x^2 = 2^2 * 3^2 * 7^2

Take the square root of both sides

x = 2 * 3 * 7

Evaluate the product

x = 42

Hence, the square root of 1764 using perfect factors is 42
