Answer:

x^2 - 3x - 40

Step-by-step explanation:

x = 8 and x = -5

x - 8 = 0 and x + 5 = 0

(x - 8)(x + 5)

x^2 + 5x - 8x - 40

x^2 - 3x - 40

Answer:  x^2 - 3x - 40

Answer: (-2, -2)

Step-by-step explanation:

Reflection over the x-axis: (x, y) → (x, -y)

(-2, 2) → (-2, -2)

x would remain the same but the y would turn negative since we're reflecting over the x-axis. The x never changes in this situation but since we're flipping it over the x-axis, they y has to be negative.

Hope this helps!

Solve the following new equation
mixer [17]

Answer:

<h3>x = 1.54 or x = - 4.54 to 2 decimal places</h3>

Step-by-step explanation:

x² + 3x - 7 = 0

Using the quadratic formula

a = 1 b = 3 c = - 7

x =  \frac{3 ± \sqrt{ {3}^{2} - 4(1)( - 7) }  }{2(1)}  \\  x =  \frac{ - 3± \sqrt{9 + 28} }{2}  \\  \\ x =  \frac{ -3 ± \sqrt{37} }{2}  \\  \\ x =  \frac{ - 3 +  \sqrt{37} }{2}  \:  \:  \:  \:  \: or \:  \:  \: x =  \frac{ - 3 -  \sqrt{37} }{2}  \\  \\ x = 1.54 \:  \:  \: or \:  \: x =  - 4.54

Hope this helps you
