Factories:x3 – 3x2 + x – 3

x3 – 3x2 + x – 3= (x3 – 3x2) + (x -3)= x2(x – 3) + 1(x – 3)= (x – 3)(x2 + 1)So we get,x3 – 3x2 + x – 3 = (x – 3)(x2 + 1)

Factories:
x³ – 3x² + x – 3

x³ – 3x² + x – 3

= (x³ – 3x²) + (x -3)

= x²(x – 3) + 1(x – 3)

= (x – 3)(x² + 1)

So we get,

x³ – 3x² + x – 3 = (x – 3)(x² + 1)

Factories:

(ax + by)² + (bx – ay)²

Factories:

ab² + (a – 1)b -1

Factories:

ab(x² + y²) – xy(a² + b²)

Factories:

x² – x(a + 2b) + 2ab
