Video help added for Find the value of (i) x^3 + y^3 – 12xy + 64, when x + y = – 4

We added video help to Find the value of (i) x^3 + y^3 – 12xy + 64, when x + y = – 4 for students who need to see the step move, not just read it.

Why this matters

Some doubts are not about the final answer. They are about the transition: why this line became the next line, why a formula was chosen, or why a shortcut is allowed.

What to do now

• Read the written solution first.
• Watch the video only where the step feels unclear.
• Try the same question again without pausing.

Use the video as a repair tool: watch the confusing part, then come back to solving.
