-2y^2 + 6y + 2 = 0
a = -2, b = 6, c = 2
x = (- b + - sqrt(b^2-4ac))/(2a)
x=(-6+-sqrt(36-4*-2*2))/-4
x=(-6+-sqrt(36+16))/-4
x=(-6+-sqrt(52))/-4
x = (-6 +- 2sqrt13)/-4
x = (3 + - sqrt13)/2

How do you know if a girl like you and what is x+10 divided by 6 = 1
strojnjashka [21]

Answer:

x = -2/3

Step-by-step explanation:

x + 10 ÷ 6 = 1

Divide

x + 1 2/3 = 1

Subtract 1 2/3

x = -2/3

Also, as a girl, we do give some signs to people that we like, we start conversations with the person, we make eye contact and then look away (at least that what I do lol), flirts with you, agrees with you, wants to spend time with you, etc.

-9 + p/2= -13 <br> (two step equations, show your work)
malfutka [58]

Answer:

p=−8

Step-by-step explanation:

Regroup terms.

p /2 −9=−13

Add 9 to both sides.

p/2  =−13+9

Simplify  -13+9 to −4.

p/2=−4

Multiply both sides by 2.

p=−4×2

Simplify  4×2  to  8

<h2>p=−8 </h2>

What are the zeros of P(m) = (m2 – 4)(m2 + 1)?
devlian [24]

Answer:

m=4, -1

Step-by-step explanation:

if i am interpreting this correctly, you are wanting to find at what value of m would the solution be zero.

so, there are two expressions that can cause an answer of 0.

1) if 0=m2-4

so solve for m2, and you get 4=m2

2) if 0=m2+1

solve for m2, and you get -1=m2

you can check your work by plugging the values back into the equation.

P(m)=(4-4)(4+1)

=(0)(5)

=0

and

P(m)=(-1-4)(-1+1)

=(5)(0)

=0
