Question : Simplify the given expression: $(1 + x)^3 + (1 – x)^3 + (–2)^3$

Option 1: $6(1 - x^2)$

Option 2: $-3(1 - x^2)$

Option 3: $-6(1 - x^2)$

Option 4: $3(1 - x^2)$

Team Careers360 19th Jan, 2024

Correct Answer: $-6(1 - x^2)$


Solution : Given expression,
$(1 + x)^3+ (1 - x)^3 + (-2)^3$
We know,
$(a+b)^3=a^3+b^3+3a^2b+3ab^2$
And $(a-b)^3=a^3-b^3-3a^2b+3ab^2$
⇒ $(1 + x)^3+ (1 - x)^3 + (-2)^3$ 
= $1+x^3+3(1)^2(x)+3(1)(x)^2+1-x^3-3(1)^2(x)+3(1)(x)^2-8$
= $1+x^3+3x+3x^2+1-x^3-3x+3x^2-8$
= $6x^2-6$
= $-6(1-x^2)$
Hence, the correct answer is $-6(1 -x^2)$.

Question : A person observes that the angle of elevation of the top of a pole of height 15 metres is 30°. What is the distance (in metres) of the person from the pole?

Option 1: $15$

Option 2: $15\sqrt3$

Option 3: $\frac{15}{\sqrt3}$

Option 4: $30$

Team Careers360 17th Jan, 2024

Correct Answer: $15\sqrt3$


Solution : Given: A person observes that the angle of elevation of the top of a pole of height 15 metres is 30°.
We know the formula, $\tan \theta=\frac{\text{Height}}{\text{Base}}$.

In $\triangle$ABC,
$\tan \angle BCA= \tan 30°$
⇒ $\frac{AB}{BC}=\frac{1}{\sqrt3}$
⇒ $\frac{15}{BC}=\frac{1}{\sqrt3}$
$\therefore BC = 15\sqrt3$
Hence, the correct
