Question

25y³+10y²+4y=

a²- a + ax - x =

(2xy + 3xz)² =

(x² - 3y)²=

(3x - 8j) (3x + 8j) =

Answer 1

Resposta:

$a) {25y}^{3} + {10y}^{2} + 4y \\ y \times ( {25y}^{2} + 10y + 4)$

$\\ \\ b) {a}^{2} - a + ax - x \\ a \times (a - 1) + x \times (a - 1) \\ (a - 1) \times (a + x)$

$\\ \\ c)(2xy + 3xz {)}^{2} \\ (2xy {)}^{2} + 2 \times 2xy \times 3xz + (3xz {)}^{2} \\ {4x}^{2} {y}^{2} + {12x}^{2} yz + {9x}^{2} {z}^{2}$

$\\ \\ d)( {x}^{2} - 3y {)}^{2} \\ ( {x}^{2} {)}^{2} - 2 {x}^{2} \times 3y + (3y {)}^{2} \\ {x}^{4} + {6x}^{2}y + {9y}^{2}$

$\\ \\ e)(3x - 8j)( 3x + 8j) \\ (3x {)}^{2} - (8j {)}^{2} \\ {9x}^{2} - {64j}^{2}$
