PLEASE I NEED HELP algebra2 lesson: solving quadratics equations

solve the equations, check your solution
1.) x^2+9=0

2.) x^2-4 = -11

1) x= 3i, x= - 3i

2) x= +i, x = - i

Step-by-step explanation:

1) x^2+9=0

(x+3i)(x-3i)=0

x= 3i, x=-3i

2) x^2-4=-11

x^2=-7

x= ±i

x= +i, x = - i

hope this helps!! :))

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
