Question

15. Factorize the following-
(1)x+ + -- +2-23 () 2a-32a (ii) 1+2ab-a?-b?
(iv) 6x +7x-3
(v)x - 3x +2 (vi) 2x+y*+82-2 V2 xy+4+2= yz -8xz
(vii) 2a?-128a
16. Evaluate: (28) + (-15) + (-13)
17. Factorise- (a) 27a + 8b +54 a²b+36 ab?
(b) 8x +64
18. If the polynomial p(x)= x-2x +3x?-ax+8 is divided by (x - 2) leaves the remainder 10,
then find the value of a.
19. Factorize-x2-3x?-10x+24.
20. Find the value of p is the polynomial p(x)=x-2x+3x* -px+3p-7 when divided by (x+1) leaves the remainder 19.
Also find the remainder when p(x) is divided by (x+2).​
