Question

Determine the number and type of solutions to the equation x^2+7x=−11.

Answer 1

^that has nth to do with my question, but ok

Answer 2

nice
im trying
lol

Answer 3

@jhonyy9

Answer 4

x^2 +7x +11 = 0

this is your quadratic ?

Answer 5

yes

Answer 6

did you heard about discriminant ?

Answer 7

yes

Answer 8

and about the roots of quadratic in function of discriminant > 0 or = 0 or < 0 ?

Answer 9

yeah,i think so

Answer 10

ok

when the discriminant D > 0 how are the roots of quadratic ?

Answer 11

so if ur asking what i think you are, then she told us if the discriminant is =0, there is one real solution, and if D>0 , then there is 2 real solutions and then if D<0, there are no real (2 imaginary) solutions

Answer 12

exactly perfect

Answer 13

so then we do
\[b^2-4ac\]

which is then going to be
\[7^2-4(1)(11)\]

Answer 14

so sorry a quadratic has always two roots

so in case when D=0 than x_1 = x_2

Answer 15

ok ?

ah

Answer 19

yes so D = ?

Answer 20

i got 5 when i solved it

Answer 21

so D = 5 > 0 result what ?

Answer 22

2 solutions to the quadratic.

but idk if there's anything else i have to do after this

Answer 23

2 real solutions
that 's all i think

Answer 24

ok, ty!

Answer 25

yw

anytime is my pleasure

bye bye
