B) y = (x + 5)2 + 3
C) y = (x + 3)2 + 5
y = (x – 5)2 + 3




Question 36

A) x = 2 and x = –15
B) x = 17 and x = 13
C) x = and x = –3
D) x = –2 and x =

D)

Answer 1

Question 39 Solve. x2 + 8x + 25 = 0 A) –4 ± 3i

Answer 2

thanks :)

Answer 3

Question 38 When solving x2 + 6x = 10 by the completing the square method, what value is added to both sides?
6x/2=3x
3x^2=9x
B) 9

Answer 4

ohh okay i see how you got it.thank you :)

Answer 5

By y = a(x - h)² + k form where (h,k) is the vertex, we can show that..

"y = (x – 3)^2 + 5" is the equation with that vertex

Answer 6

A) y = (x – 3)2 + 5

Answer 7

thank you
