Question

If x4 + px3 + rx + s2 is a perfect square then, ps = ____

Answer 1

is it X^4 + px^3 + rx + 2s??

Answer 2

and is that you in the picture?

Answer 3

yess but no 2s its
s^2

Answer 4

the answer is 'r'

Answer 5

its not

Answer 6

the answer is R, sorry

Answer 7

if u consider a quad eqn x^2 + ax + b and the then square it, you get
x^4 + (2a)x^3 + (a^2 + 2b)x^2 + 2abx + b^2
if u compare the coefficients with ur own equation,
p=2a
s=b
so ps = 2ab, which is equal to r in ur eqn (coeff of x)
hence ps=r

Answer 8

@him1618: Great you got it 'right' this time :-)

Answer 9

no there were external pressures to deal with the first time i squared it
