Question

fatore: A) a²+2a+1
B) x²-20x+100
C) 16x²+56x+49
D) 9x²-84xy+196y²
E) 441+42x+x²

Answer 1

A)
$a {}^{2} + 2a + 1 = (a + 1) {}^{2}$
B)
$x {}^{2} - 20x + 100 = (x - 10) {}^{2}$
C)
$16x {}^{2} + 56x + 49 = (4x + 7) {}^{2}$
D)
$9x {}^{2} - 84xy + 196y {}^{2} = (3x - 14y) {}^{2}$
E)
$441 + 42x + x {}^{2} = (x + 21) {}^{2}$
