Question

खालील बहुपदीचे अवयव काढा.

(x2 − 2x + 3) (x2 − 2x + 5) − 35

Sum

Solution

(x2 – 2x + 3) (x2 – 2x + 5) – 35 

x2 – 2x = z मानू.

∴ (x2 - 2x + 3) (x2 - 2x + 5) - 35

= (z + 3) (z + 5) - 35

= z2 + 5z + 3z + 15 - 35

= z2 + 8z - 20

= z2 + 10z - 2z - 20

= z (z + 10) - 2 (z + 10)

= (z + 10) (z - 2)

= (x2 - 2x + 10) (x2 - 2x - 2)   ...(z = x2 - 2x ठेवून)
