Question

desenvolvendo o produto notavel (0,5+1,5x)² encontramos?

Answer 1

produto notável

( 0,5 + 1,5x)²=

(0,5)² + 2.(0,5).(1,5x) +(1,5x)²=

0,25 +2(0,75x) +2,25x²=

0,25 + 1,5x  + 2,25x²

Answer 2

Oie, Td Bom?!

$= (0,5 + 1,5x) {}^{2}$

$= ( \frac{1}{2} + \frac{3}{2} x) {}^{2}$

$= ( \frac{1}{2} ) {}^{2} + 2 \: . \: \frac{1}{2} \: . \: \frac{3}{2} x + ( \frac{3}{2} x) {}^{2}$

$= \frac{1}{4} + \frac{3}{2} x + \frac{9}{4} x {}^{2}$

$\boxed { = 0,25 + 1,5x + 2,25x {}^{2} }$
