Question

An algebraic expression is subtracted from −7j3 + 12jk3 + 11k3 –8j2k2 to get −15k3j –4k3 + 12k2j2–5j3. What do we getif the same expression is subtracted from 15jk3 + 15k3 –7j3 + 10j2k2?​

Answer 1

Answer:

⇒ Product of x and a = x×a=ax

⇒ Product of b and y = b×y=by

⇒ Product of x and a subtracted from the product of b and y = by−ax.

∴ Required algebraic expression is by−ax.
