Answer:

Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

(3a-1/2)(3a-1/2)

(3a-1/2)^2

(3a)^2 + (1/2)^2 - 2(3a)(1/2) ---------- (using identity (a-b) ^2 = a^2 + b^2 - 2ab)

9a^2 + 1/4 - 3a

9a^2 - 3a + 1/4

Answer 2

$\Huge\boxed{question}$

(3a-1/2)( 3a-1/2)use a suitble to get a each of the following product

$\Huge\boxed{identity}$

$( a \: - \: b)^{2} \: = \: {a}^{2} \: - 2 \: a \: b \: + {b}^{2}$

$\Huge\boxed{solution}$

By using identity

$(3 \: a - \frac{1}{2} )^{2}$

$= \: (3 \: a)^{2} \: - \: 2 \: \times \: 3 \: a \: \times \: \frac{ - 1}{2} + \: \\ (\frac{ - 1}{2})^{2}$

$\rightarrow \: \: \: {9a}^{2} \: -3a \: + \: \frac{1}{4}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{final \: \: Answer}$

$\rightarrow \: \: \: \: \: \boxed{ {9a}^{2} \: - \: 3a \: + \: \frac{ 1}{4} }$
