(x+5)(x^2-5x+25)

Step-by-step explanation:

दिया गया समीकरण   x^3+125 को a^3+b^3  के रूप में बदलने पर हमें इस समीकरण का गुणनखंड प्राप्त होता है |

a^3+b^3=(a+b)(a^2-ab+b^2)

a=x       और    b=5

x^3+5^3=(x+5)(x^2-5x+25)

x³  + 125 =(x +5)(x² - 5x + 25)

Step-by-step explanation:

x³  + 125

= x³ + 5³

a³ + b³ = (a + b) (a² + b²  - ab)

a = x

b = 5

= (x +  5)(x² + 5²  - x*5)

=(x +5)(x² - 5x + 25)

x³  + 125 =(x +5)(x² - 5x + 25)
