Question

use the discriminant to find the number and kind of solutions for the equation 2x2 + 7x = 10

Answer 1

The answer is this :
4+7x=10
7x=10-4
7x=6
x=6/7
Did you want it ?!:)

Answer 2

i wrote that equation wrong.. it is \[2x ^{2} + 7x = 10\]

Answer 3

Is this your question ?

Answer 4

yes

Answer 5

Ok !
We have :
2x^2+7x-10=0

Answer 6

It s a 2th equetion !
You should find X in this way but remamber we have -x and +x .!

Answer 7

Firs find \[Deltab\]:
To find it can use this formula :
Delta = b^2-4ac
2=a
-10=c
7=b
Then to find x :
Understand ?

Answer 8

@annalizz12

Answer 9

D=b^2-4ac=7^2-4*2*(-10)=49+80=139
If D=0 roots are real and equal
if D is positive and a perfect square,then roots are real rational and different.
If D is positive and not a perfect square roots are real ,irrational and different.
If D is negative, then roots are not real,they are imaginary.

Answer 10

hey tthe answer is that u have to ask ur theacher just kidding lol:)

Answer 11

correction
49+80=129

Answer 12

ok ok ok ok ok ok ok ok ok
