Answer:

157

Step-by-step explanation:

You just have to take 73+84, and here is the equation.

73+84=157

First, add the numbers in the ones place.

3+4=7

Now you know that the ones place is 7, we find the tens place.

7+8=15

Since only a 1-digit number can fill up a place, we bring the one over to the hundreds place.

Hence, the answer 157.

If the discriminant of a quadratic equation is equal to -8, which statement describes the roots?

Dovator [93]

Keywords

quadratic equation, discriminant, complex roots, real roots

we know that

The formula to calculate the roots of the quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}}{2a}$

where

The discriminant of the quadratic equation is equal to

$b^{2}-4ac$

if $(b^{2}-4ac)> 0$ ----> the quadratic equation has two real roots

if $(b^{2}-4ac)=0$ ----> the quadratic equation has one real root

if $(b^{2}-4ac)< 0$ ----> the quadratic equation has two complex roots

in this problem we have that

the discriminant is equal to $-8$

the quadratic equation has two complex roots

therefore

the answer is the option A

There are two complex roots

Lerok [7]

Answer:

−8s4u2+2s2ux+6x2

Step-by-step explanation:

=(6x+8us2)(x+−s2u)

=(6x)(x)+(6x)(−s2u)+(8us2)(x)+(8us2)(−s2u)

=6x2−6s2ux+8s2ux−8s4u2

=−8s4u2+2s2ux+6x2

galben [10]

So we are finding the difference btween 5x-3 and 3x+1.
(5x-3)-(3x+1)

Let's subtract the x's first.
5x-3x=2x
Now the numbers.
-3-1=-4
Now, we need to put 2x and -4 together.

The expression would be 2x-4.
