Question

помогите пожалуйста ​

Answer 1

$25 {x}^{2} - 50x + 25 = {( - 5x + 5)}^{2}$

$4 {x}^{2} + 32x + 64 = (2x + 8) ^{2}$

$81 {x}^{2} - 54x + 9 = {(9x - 3)}^{2}$

$64 {x}^{2} + 32x + 4 = {(8x + 2)}^{2}$

$9 {x}^{2} - 4 = (3x + 2)(3x - 2)$

$25 {x}^{2} - 30x + 9 = {(5x - 3)}^{2}$

$49 {x}^{2} - 9 = (7x + 3)(7x - 3)$

$64 {x}^{2} + 112x + 49 = {(8x + 7)}^{2}$

$4 {x}^{2} - 36x + 81 = {(2x - 9)}^{2}$
