Answer:

(3x-2)

Step-by-step explanation:

3x² + 4x - 4

look for two factors whose product is (3)(-4)=<em>-12</em> and sum is +4

The factors will be +6 and -2

substitute these factors inplace of 4x to get:

3x² - 2x + 6x - 4

then factorize:

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

finally we get factors: (3x-2)(x+2)

Nady [450]
The problem can be solved by <span>proportion as following
</span>
<span>For every 15 columns of news stories in a newspaper, 4 columns of ads are required
</span>
If a newspaper contains 300 columns of news stories, x columns of ads are required
∴ 15 : 4 = 300 : x
∴ \frac{15}{4} =  \frac{300}{x}
By using cross multiplication
∴ 15 x = 4 * 300
∴ 15 x = 1,200
∴ x = 1,200/15 = 80

So, the number of <span>columns of ads must it have = 80 </span>
