Question

1*) Efetue :

a) ( x + 7 )2 =
b) ( 5 + 2 m )2 =
c) ( a + 3 x )2 =
d) ( 10 x + y )2 =
e) ( 5 x2 + 1 )2 =
f) ( 11 + Pq )2 =
g) ( x + 0,5 )2 =
h) ( x + 1/2 )2 =

Answer 1

a) ( x + 7 )² = x²+14x+49

b) ( 5 + 2 m )² = 4m²+20m+25

c) ( a + 3 x )² = 9x²+6a+a²

d) ( 10 x + y )² = 100x²+20xy+y²

e) ( 5 x² + 1 )² = 25x^4+10x²+1

f) ( 11 + Pq )² = 121+22Pq+(Pq)²

g) ( x + 0,5 )² = x²+x+0,25

h) ( x + 1/2 )² = x²+x+(1/4)

Answer 2

a) ( x + 7 )² = x²+14x+49
b) ( 5 + 2 m )² = 4m²+20m+25
c) ( a + 3 x )² = 9x²+6a+a²
d) ( 10 x + y )² = 100x²+20xy+y²
e) ( 5 x² + 1 )² = 25x^4+10x²+1
f) ( 11 + Pq )² = 121+22Pq+(Pq)²
g) ( x + 0,5 )² = x²+x+0,25
h) ( x + 1/2 )² = x²+x+(1/4)
