Question

Нужно представить в виде квадрата:
a²+8a+16
9x²-6x+1
121m²-88mn+16n²
24ab+36a²+4b²

Answer 1

1)
${a}^{2} + 8a + 16 = (a + 4 {)}^{2}$

2)
$9 {x}^{2} - 6x + 1 =( 3x + 1 {)}^{2}$

3)
$121 {m}^{2} - 88mn + 16 {n}^{2} = \ (11m - 4n {)}^{2}$

4)
$24ab + 36 {a}^{2} + 4 {b}^{2} = (6a + 2b {)}^{2}$
