Question

am nevoie rapid plssss​

Answer 1

x² - 5x = x(x - 5)

3x$^{10}$ + 9x$^{8}$ = 3x$^{8}$ (x² + 3)

x (x+1) -x -1 = x² + x - x - 1 = x² - 1 = (x+1) × (x-1)

x² (x+1) + x (x+1)² = x (x+1) (x + x + 1) = x ×(x+1)× ( 2x + 1)

xy - x - y + 1 = x (y-1) - (y-1) = (y-1) ×(x-1)

9xy + 3x -3y -1 = 3x ( 3y + 1) - (3y + 1) = (3y+1)× (3x - 1)

25x² - 49 = (5x - 7) × (5x + 7)

(x-2)² - 4x² = (x - 2 - 2x) ( x- 2 + 2x) = (-x-2)× (3x -2)

x² + 6x + 9 - y² = (x+3)² - y² = (x+3 - y) × (x+3 +y)

x² + 7x + 6 = x² + 6x + x + 6  = x(x+6) + x + 6 = (x+6) × (x+ 1)

x² -5x + 6 = x² -2x - 3x + 6 = x(x-2) -3(x-2) = (x-2) × (x-3)

x² + 2x -3 = x² + 3x - x -3 = x(x+3) -(x+3) = (x+3) × (x-1)

2x²+x - 1 = 2x² + 2x - x -1 = 2x (x+1) - (x+1) = (x+1) × (2x-1)

x³ + x² -16x - 16 = x²(x+1) -16(x+1) = (x+1) × (x² -16) = (x+1) × (x-4) × (x+4)

Sper ca te-am ajutat !
