What are the solution(s) to the quadratic equation 40 - x2 = 0?
nekit [7.7K]

Step-by-step explanation:

40 -  {x}^{2}  = 0 \\  \therefore \:  {x}^{2}  = 40 \\ \therefore \: x =  \pm \sqrt{40} \\  \therefore \: x =  \pm \sqrt{4 \times 10} \\  \huge \red{ \boxed{\therefore \: x  = \pm 2\sqrt{10}}}

Help on this please
eimsori [14]

Answer:

Opening: Opens upwards

Axis of Symmetry: -7/2

Vertex: (-7/2, -81/4)

X - intercepts: (1, 0) and (-8, 0)

Y - intercept: (0, -8)

Step-by-step explanation:

Opening: 'a' is greater than zero

Axis of Symmetry:

\frac{-7}{2(1)} =\frac{-7}{2}

Vertex:

y= (\frac{-7}{2})^{2} +7(\frac{-7}{2}) -8\\y= (\frac{49}{4}) +(\frac{-49}{2}) -8\\y= \frac{49}{4} +\frac{-98}{4} -8\\y=\frac{-49}{4}-8\\y = \frac{-81}{4}

X - intercepts:

(x-1)(x+8)

x = 1 and x = -8

Y - intercept: (0, -8)

y= 0^{2} +7(0) -8\\\\y= -8\\
