ii) (a - 1)x² + a²xy + (a + 1)y
iii) x-qx - p5pq - 69
32 (0+ )-(--)-
1Xx2-x) y2 + y =(x2 + x)​

Answer 1

Answer:

[a] (i) 3x(4x−5)+3

=3×3(4×3−5)+3

=9(7)+3=66

(ii) 3x(4x−5)+3

=3×21(4×21−5)+3

=23(2−5)+3

=2−3

[b] (i) a(a2+a+1)+5

=0+5

=5

(ii) a(a2+a+1)+5

=1(3)+5

=8

(iii) a(a2+a+1)+5

−1(1−1+1)+5

−1+5

=4
