Question

trinômio do quadrado perfeito
a=x²-4x+4
b=x²-6x+9
c=x²-10x+25
d=m²+8m+16
e=p²-2p+1
f=k²+14k+49

Answer 1

a=x²-4x+4 = ( x-2 ) ²


b=x²-6x+9 = ( x - 3 ) ²


c=x²-10x+25 = ( x - 5 ) ²


d=m²+8m+16 = (m + 4 ) ²


e=p²-2p+1 = ( p - 1 ) ²


f=k²+14k+49  = ( k + 7 ) ²

Answer 2

a)
$x^{2} - 4x + 4 \\ \\ \\ (x - 2)^2$

b)
$x^{2} -6x + 9 \\ \\ \\ (x - 3)^2$

c)
$x^{2} - 10x + 25 \\ \\ \\ (x - 5)^2$

d)
$m^2 + 8m + 16 \\ \\ \\ (m + 4)^2$

e)
$p^2 - 2p + 1 \\ \\ \\ (x - 1)^2$

f)
$k^2 + 14k - 19 \\ \\ \\ (k + 7)^2$
