QUESTION: if p=4,q=3,andr= -2,then find the value of the algebraic expression
p²+q²-r²
------------
pq+qr-pr​​​

Answer 1

p²+q²-r²=4²+3²-(-2)²=21.

pq+qr-pr=(4×3)+(3×-2)-(4×-2)=14.

Answer 2

Answer:

hiii

good morning e 2EP is nonsingular when Delta0 is nonsingular. ... p2(x2) y2''(x2) + q2(x2) y2'( x2) + r2(x2) y2(x2) = lambda s2(x2) y2(x2) + mu s2( x2

hope it help

thank you

have a great day
