Perform the specified operations on the polynomials: Subtract 2x2−3xy+4y2from 3x2−5xy−6y2

tankabanditka [31]

Answer:

Solution to the given expression is $(x^2 -10y^2 -2xy)$

Step-by-step explanation:

Here, the given expression are:

$P(x) = 2x^2- 3xy+4y^2\\Q(x) = 3x^2 - 5xy-6y^2$

To Solve for : Q(x) - P(x)

Now substitute the value of P(x) and Q(x) , we get:

$Q(x) - P(x) = P(x) = (3x^2 - 5xy-6y^2) - (2x^2- 3xy+4y^2)\\= 3x^2 - 5xy-6y^2 - 2x^2+3xy-4y^2\\=x^2-10y^2-2xy\\\implies Q(x) - P(x) = (x^2-10y^2-2xy)$

Hence solution to the given expression is $(x^2 -10y^2 -2xy)$

vladimir2022 [97]

Answer:

At the end krisi will receive 550

Step-by-step explanation:

We have given that krisi took $500

So the principle amount P = $500

Rate of interest r = 5%

Time t = 2 years

We know that simple interest is given by

$simple\ interest=\frac{P\times r\times t}{100}=\frac{500\times 5\times 2}{100}=$50$

So the amount which he receive = 500 +50 =550

So at the end krisi will receive 550
