Question

2. If p = 1,9 = -1, Find the value of:
१)p²-q²

ii) p3 - p2 + q? - pq
. If a = -3 then find the value of.
i) a +5+2 (a -1)
ii)
-(a+2)+3a​

Answer 1

Step-by-step explanation:

1 . (1)2-(-1)2

= 1-(1 )

= 1-1

= 0

ii . p3-p2+q-pq

= (1)3 -(1)2+(-1)-(1)(-1)

= 1 +1-1-(-1)

= 2 -1+1

= 2

if a= -3

I . a+5+2(a-1)

= -3+5+2a-2

=2 -2 +2a

=2a

=2×(-3)

= -6

ii . -(a+2)+3a

= -(-3+2) +3(-3)

= -(-1)+(-9)

= 1-9

=-8
