Which expression is equivalent to x^4 - 12x^2 + 36?
QveST [7]
So the answer is
(<span>x^2 plus or minus 6)(x^2 plus or minus 6)
an easy way to do this is to only look at plus or minus 6
x^4 <u><em>- 12</em></u>x^2 + <u><em>36   (-12 and 36)
</em></u><em />

<u><em /></u>6 x 6 = 36
<em />6 + 6 </span>≠ -12              (x^2 + 6)(x^2 + 6) is incorrect        
<span><u><em>
</em></u><em><u /></em><u />
6 x -6 </span>≠ 36
<span><em />6 + -6 </span>≠ -12             (x^2 - 6)(x^2 + 6) is incorrect
<span><em /><em>
</em><em />-6 x -6 = 36
<em />-6 + -6 = -12         </span><span>(x^2 - 6)(x^2 - 6) is correct
</span><u><em>
the answer is (1)

Which function has x-intercepts of 3 and 8 and contains the point (–1, –2)?
mojhsa [17]
This is how you do it.

y = a(x - 3)(x - 8) 
<span>-2 = a(-1 - 3)(-1 - 8) </span>
<span>-2 = 36a </span>
<span>- 1 / 18 = a </span>
<span>y = ( - 1 / 18)(x^2 - 11x + 24) </span>
<span>y = (- 1 / 18)x^2 + (11 / 18)x - (3 / 2)
</span>

What is the cash payment of a article costing RS.2020 allowing a discount of Rs.20 and levying 13% VAT?​
belka [17]

The cash payment for the article is RS. 2,260.

A discount reduces the price of an item. The article becomes cheaper after the discount.

Cost of the article after the RS. 20 discount = RS. 2020 - 20 = RS 2000

VAT means value added tax. VAT increases the price of an item. The cost of the article increases by 13% after the  VAT is levied,

Cost of the article = (100 + 13%) x 2000

1.13 x 2000 = RS 2,260.
