Question

9. (2x + x2-5x - 2) by (2x+3)​

Answer 1

Answer:

$2x + 3 = 0 \\ 2x = - 3 \\ x = \frac{ - 3}{2} \\ p(x) = 2x + x2 - 5x - 2 \\ p (\frac{ - 3}{2}) =2 \times \frac{ - 3}{2} + \frac{ - 3}{2} \times 2 - 5 \times \frac{ - 3}{2} - 2 \\ = - 3 + ( - 3) + \frac{15}{2} - 2 \\ = \frac{ - 6 - 6 + 15 - 4}{2} = \frac{ - 16 + 15}{2} = \frac{ - 1}{2} ans$
