Quadratic equation: ax² + bx + c =0
x' = [-b+√(b²-4ac)]/2a and x" = [-b-√(b²-4ac)]/2a
6 = x² – 10x ; x² - 10x -6 =0
(a=1, b= - 10 and c = - 6
x' = [10+√(10²+4(1)(-6)]/2(1) and x" = [10-√(10²+4(1)(-6)]/2(1)
x' =5+√31 and x' = 5-√31
Answer. Second option: f(x)=(x+2)(x−(−1+i2√))(x−(−1−i2√))

Answer:
C
Step-by-step explanation:
Answer:
XY = 150
Step-by-step explanation:
AB = 8
W Z = 80
SF = 10
8 x 10 = 80
So if BC = 15
XY = 15 x 10 = 150
Answer:
yes
