Answer:

\large\boxed{x^2+8x+19=0\Rightarrow(x+4)^2=-3}

x^2+8x+19=0\qquad\text{subtract 19 from both sides}\\\\x^2+8x=-19\\\\x^2+2(x)(4)=-19\qquad\text{add}\ 4^2\ \text{to both sides}\\\\x^2+2(x)(4)+4^2=-19+4^2\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\(x+4)^2=-3

Simplify 3a(a^2-3a+4)-4(3a^3-2a^2)
bogdanovich [222]

Answer:

<h2>−9a³ − a² + 12a</h2>

Step-by-step explanation:

3a(a²-3a+4)-4(3a³-2a²) = 3a³ − 9a² + 12a − 12a³ + 8a²

                                     = (3a³ − 12a³) + (− 9a² + 8a²) + 12a  

                                     = −9a³ − a² + 12a
