Question

1. 6(x + 2)2 – 5(x + 2) - 4​

Answer 1

Step-by-step explanation:

$6 {(x + 2)}^{2} - 5(x + 2) - 4$

$= 6( {x}^{2} + 2(x)(2) + {2}^{2} ) - 5(x + 2) - 4$

$= 6( {x}^{2} + 4x + 4) - 5x - 10 - 4$

$= 6 {x}^{2} + 24x + 24 - 5x - 10 - 4$

$= 6 {x}^{2} + 24x - 5x + 24 - 10 - 4$

$= 6 {x}^{2} + 19x + 10 \: (ans)$
