If the discrimination of equation is equal to -8, which statement describes the roots ?

Mathematics
1 answer:
kvv77 [185]3 years ago
4 0

Answer:

see explanation

Step-by-step explanation:

The value of the discriminant informs about the nature of the roots of a quadratic function.

The discriminant Δ = b² - 4ac

• If b² - 4ac > 0, then roots are real and distinct

• If b² - 4ac = 0, then roots are real and equal

• If b² - 4ac < 0, then the roots are not real

Hence for b² - 4ac = - 8, then roots are not real

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\\

it just means that 22.2 needs to be multiplied by 10, 5 times, so just move the decimal five to the right.
