2x+7=27 and 3x+1=28 does 2x+7= 3x+1
Savatey [412]
Hey there!

2x + 7 = 27
2x = 20
x = 10

3x + 1 = 28
3x = 27
x = 9

The values for both of these equations are 9 and 10; therefore, the answers are not equivalent.

I hope this helps!

If the discriminant of a quadratie equation is equal to -8 which statement describes the root
NemiM [27]

Answer:

there are two complex roots

Step-by-step explanation:

Recall that for a quadratic equation

y = ax² + bx + c

the solution given by the quadratic formula is

x = ( -b ± √discriminant) / 2a

if the discriminant is negative, the radical term will become √ (negative number), which we know gives complex solutions. Hence we can eliminate real roots as possible answers.

Also notice that the "±" sign in the quadratic formula means that you will get 2 possible solutions:

x = ( -b + √discriminant) / 2a

or

x = ( -b - √discriminant) / 2a

Hence we know we will get 2 solutions.

Combining our findings, we can conclude that if the discriminant is negative, we will get 2 complex roots.
