Question

3x(4x-5)+3 if x=1/2​

Answer 1

Step-by-step explanation:

12x^2 - 15x +3

= 12(1/2)^2 -15(1/2) + 3

=12*1/4 - 15/2 +3

=12/4 - 15/2 +3/1

= 12-30+13 / 4

= 12-18/4

= -6/4

= -3/2

So the ans is -3/2

Answer 2

$\huge{\mathfrak{\underline{\red{answer}}}}</p><p>$

$= 3x(4x - 5+3)$

$\large{\mathfrak{\underline{\red{if \: x = \frac{1}{2} }}}}</p><p>$

$= 3( \frac{1}{2} )(4( \frac{1}{2} ) - 5) +3$

$= \frac{3}{2} (2 - 5)$+3

$= \frac{3}{2} ( - 3)$+3

$= \frac{ -9}{2}+3$

$= \frac { -9+6}{2}$

$= \frac { -3}{2}$
