Question

use sutaible identities to find the following
(-5x+3)(3+51).​

Answer 1

Hey manoj!! How r u?? May be fine.

See, this is the answer:-

ATQ, (-5x+3)(3+51)

= (-5x+3)54

= (-5x×54)+(3×54)

= -270x+162.

I think this answer could be. If possible!!

But, I think that question may be wrong. How we can use the identity??
