PLEASE HELP MEEEEE!!!!!!!!!!! Solve this quadratic equation. x 2 + 5x + 3 = 0

andreev551 [17]

Answer:

$x1=\frac{-5+\sqrt{13}}{2}\\ \\x2=\frac{-5-\sqrt{13}}{2}$

Step-by-step explanation:

x² + 5x + 3 = 0

x = (- 5 +/- √5² - 4x1x3)/2x1

= (-5+/-√13)/2

x₁ = (- 5 + √13)/2

x² = (- 5 - √13)/2

G(b) = 5b- 9 h(b) = (b - 1)^2 Evaluate. (hog)(-6) =

laiz [17]

Given:

The two functions are:

$g(b)=5b-9$

$h(b)=(b-1)^2$

To find:

The value of $(h\circ g)(-6)$ .

Solution:

We have,

$g(b)=5b-9$

$h(b)=(b-1)^2$

We know that,

$(h\circ g)(b)=h(g(b))$

$(h\circ g)(b)=h(5b-9)$

$(h\circ g)(b)=[(5b-9)-1]^2$

$(h\circ g)(b)=[5b-10]^2$

Putting $b=-6$ , we get

$(h\circ g)(-6)=[5(-6)-10]^2$

$(h\circ g)(-6)=[-39-10]^2$

$(h\circ g)(-6)=[-49]^2$

$(h\circ g)(-6)=2401$

Therefore, the value of $(h\circ g)(-6)$ is 2401.
