Question : If $(x–4)(x^2+4x+16)=x^3–p$, then $p$ is equal to:

Option 1: 27

Option 2: 8

Option 3: 64

Option 4: 0

Team Careers360 19th Jan, 2024

Correct Answer: 64


Solution : Given: $(x–4)(x^2+4x+16)=x^3–p$
Formula: We know that $a^3–b^3=(a–b)(a^2+ab+b^2)$
Solution:
$x^3–p=(x–4)(x^2+4x+16)$
⇒ $x^3−p=(x^3−4^3)$
⇒ $p = 4^3$
So, $p = 64$.
Hence, the correct answer is 64.

Option 1: 560

Option 2: 640

Option 3: 480

Option 4: 720

Team Careers360 15th Jan, 2024

Correct Answer: 560


Solution : Given: $(a+b+c)=20$ and $a^2+b^2+c^2=152$
We know the identity,
$(a+b+c)^2 = a^2 + b^2 + c^2 + 2ab + 2bc + 2ca$
$(a+b+c)^2 = a^2 + b^2 + c^2 + 2(ab + bc + ca)$
⇒ $20^2=152+2(ab + bc + ca)$
⇒ $ab + bc +
