Question

m) (2x + 5)2 - (2x - 52
(iv) (4m + 5n) + (5m + 4)
4. Simplify.
a) (a - b)
(m) (7m - 8n) + (7m + 8n)
(v) (2.5p - 1.59) - (1.5p - 2.59)
(vi) (ab + bc) - 2ab-c
5. Show that.
(1) (3x + 7) - 84x = (3x - 7)-
(vii) m - m 2mm
n (9p-57) +180pq = 9p+50

(iv) (4pq + 39) - (4pq - 39) = 48pq?
(v) (a - b)(a + b) + (b-c)(b + c) + (c-a)(c + a) = 0​
