We can factor this using the AC method.

We can split the middle term using the factors 4 and -9

x^2 + 4x - 9x - 36

Factor by grouping.

x(x + 4) - 9(x + 4)

<h3><u>(x - 9)(x + 4) are the factors of this polynomial.</u></h3>

Answer:

E= $10^{18}$ Joules

Step-by-step explanation:

1) Olá! Adicionando dados faltantes ao enunciado, como a fórmula dada: $M=\frac{2}{3}log(\frac{E}{E_{0}})\\$ e corrigindo a quantidade de Energia inicial: $10^{4,5}$ Vamos seguir aplicando a fórmula, lembrando das propriedades de logaritmo.

$M=\frac{2}{3}log(\frac{E}{E_{0}})\\9=\frac{2}{3}log(\frac{E}{10^{4,5}})*3\\27=2log(\frac{E}{10^{4.5}})\\log(\frac{E}{10^{4.5}})^{2}=27\\(\frac{E^{2}}{10^{9}})=10^{27}\\E^{2}=10^{27}*10^{9}\Rightarrow E=\sqrt{10^{36}}\rightarrow E=10^{18} Joules$

Answer:

y-intercept: (0, 5)

Step-by-step explanation:

This parabola has an equation of -x² + 4x + 5.

It's y-intercept is (0, 5).

It's x-intercepts or roots are (-1, 0) and (5, 0).

It's vertex is (2, 9).

___________________________________

Keep in mind that the y-intercept is when x = 0.
