Answer 1

@AlexandervonHumboldt2

Answer 2

the quadratic formula is (-b +- sqrt(b^2-4ac))/2a

Answer 3

either ( x - 8 ) = 0 or ( x - 2 )= 0

Answer 4

nope

Answer 5

@TheSmartOne is it going to be +5 and +i or -5 and -i?

Answer 6

Quadratic Formula is \(\Huge\sf \frac{-b \pm \sqrt{b^2-4ac}}{2a}\)

Answer 7

\(\sf a=1\\ b=-10 \\c=36\)

Answer 8

Plug in the numbers and we get
\(\sf \LARGE\frac{ -(-10) \pm \sqrt{ (-10)^2 - 4 \cdot 1 \cdot 36} }{ 2 \cdot 1 }\)

Answer 9

And just simply that and tell me what you get @vera_ewing
