Question

---3) 8b3 – 363 + 17b – 363 - 8b - 5BY: 4) 3p2 + 5pc – 7c2 – 6pc + 12p2​

Answer 1

8b³-731+11b = 8b³+11b-731

3p²-7c²-pc+12p² = 15p²-7c²-pc

Answer 2

To simplify the given expressions, let's combine like terms:

1. 8b3 – 363 + 17b – 363 - 8b - 5BY:

Combining like terms, we can add or subtract the coefficients of the same variables:

8b3 - 8b + 17b - 363 - 363 - 5BY

Combining the b terms, we have:

(8b3 - 8b + 17b) - 5BY

Simplifying further:

8b3 + 9b - 5BY - 726

Therefore, the simplified expression is 8b3 + 9b - 5BY - 726.

2. 3p2 + 5pc – 7c2 – 6pc + 12p2:

Combining like terms, we add or subtract the coefficients of the same variables:

(3p2 + 12p2) + (5pc - 6pc) - 7c2

Simplifying further:

15p2 - pc - 7c2

Thus, the simplified expression is 15p2 - pc - 7c2.
