Factorise 6x²-14x-12​
maksim [4K]

Answer:

2(x - 3)(3x + 2)

Step-by-step explanation:

Given

6x² - 14x - 12 ← factor out 2 from each term

= 2(3x² - 7x - 6) ← factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × - 6 = - 18 and sum = - 7

The factors are - 9 and + 2

Use these factors to split the x- term

3x² - 9x + 2x - 6 ( factor the first/second and third/fourth terms )

= 3x(x - 3) + 2(x - 3) ← factor out (x - 3) from each term

= (x - 3)(3x + 2)

Thus

3x² - 7x - 6 = (x - 3)(3x + 2) and

6x² - 14x - 12 = 2(x - 3)(3x + 2) ← in factored form

Quickly IT is Due an a hour PLease show work show me how to do it and No links
djyliett [7]

Answer: 4

Step-by-step explanation:

-6x = -24    divide both sides by -6 to isolate x

x = -24/-6

x = 4

Checking my work (plug in 4 for x and solve)

-6x = -24

-6(4) = -24

-24 = -24    it's correct!

Find the measure of the supplement of a<br> 33° angle.<br> 
Anvisha [2.4K]

Answer:

I can't see them but whichever one is 157 is the correct angle

Step-by-step explanation:

Supplementary angles are angles that equal 180 degrees.

180 - 33 = 157

So whichever angle equals 157 degrees, that is the correct one
