Step-by-step explanation:
(1) (2a + 5)(3a - 2) + (a + 2)(20 - 3)
(ii) (3a + 2)(2a + 3) - (4a - 3)(2a - 1)
(iii) (2a + 3b)(3a + 4b) - (7a + 3b)(a + 2b)
(iv) (a? - 3a + 2)(5a - 2) - (3a + 4a - 5)(2a - 1)
(v) (2a - b + c)(a - 2b) - (3a + 2b - c)(2a - b)
(vi) (3a - 2)(2a - 1)(3a + 5)
(vii) (5 - a)(- 2a + 3)(4 - 3a)Simplify:
(1) (2a + 5)(3a - 2) + (a + 2)(20 - 3)
(ii) (3a + 2)(2a + 3) - (4a - 3)(2a - 1)
(iii) (2a + 3b)(3a + 4b) - (7a + 3b)(a + 2b)
(iv) (a? - 3a + 2)(5a - 2) - (3a + 4a - 5)(2a - 1)
(v) (2a - b + c)(a - 2b) - (3a + 2b - c)(2a - b)
(vi) (3a - 2)(2a - 1)(3a + 5)
(vii) (5 - a)(- 2a + 3)(4 - 3a
