(X^2+y^2)^2 polynomial identify. Simplify

Alexxx [7]

Answer:

$(x^{2}+ y^{2})^{2} =x^{4}+2x^{2}y^{2}+y^{4}$

Step-by-step explanation:

(X^2+y^2)^2 polynomial identify. Simplify

i.e

$(x^{2}+ y^{2})^{2} = ?$

Solution:

We have the identity,

$(A+B)^{2}=A^{2}+2AB+B^{2}$

In the Question

$A=x^{2}$

$B=y^{2}$

Substituting in the identity we get

$(x^{2}+ y^{2})^{2} =(x^{2})^{2}+2(x^{2})(y^{2})+(y^{2})^{2}$

Also we have

$(x^{a})^{b} =x^{a\times b}$

$(x^{2}+ y^{2})^{2} =x^{4}+2x^{2}y^{2}+y^{4}$ Which is the required

Help anyone pls? don’t quite understand

FrozenT [24]

I’m not sure but this is what I would do

Runner A (unit rate / constant of proportionality):
54 feet divided by 4.5 seconds = 12 feet per second

Runner B (unit rate / constant of proportionality): 300 feet divided by 20 seconds (It looks like the end point of the line lands between 300 feet and 20 seconds) = 15 feet per second

Unit Rate:
Runner A = 12 feet per second
Runner B = 15 feet per second

Faster Runner:
Runner B is the faster runner as he can run a further distance than Runner A in one second.
