Examples 4 to 6

(4) If  m  =  – 28,   and  n  =  20,  find the value of  9m2 +  24mn  +  16n2.

Soln. 9m2  +  24mn  +  16n2  =  ( 3m  +  4n )2  =  ( – 84 + 80 )2  =  16.

Examples 1 to 3

(1) If  a + b  =  9  and  a – b  =  5,  find   a2 +  b2   and  ab.

Soln. 2( a2+b2 ) =  (a + b) 2 +  (a – b) 2

=    (9) 2 +  (5) 2

=    1…

Remainder Theorem

Remainder Theorem  :   If an expression  f(x)  is divided by (x – a), then the remainder  is  f(a).

 e.g. Is  x + 2  a factor of   5x2 –  3x  –  14  ?

Factor  Theorem

Factor  Theorem  :   If  f(x)  is completely divisible by (x – a), then  f(a)  =  0.

Thus,  (x – a) is a factor of   f(x)
