Question

3x + 14x - 5 =0 solve using the quadratic formula

Answer 1

is 3x squared?

Answer 2

we need one term squared (a) one variable not squared (b) and one coefficient (c)

Answer 3

yeah

Answer 4

so it is squared? brilliant

Answer 5

yeah typo

Answer 6

A = 3
B = -14
C = -5
Accordingly, B2 - 4AC =
196 - (-60) =
256

14 ± √ 256
x = ——————
6
The prime factorization of 256 is
2•2•2•2•2•2•2•2
√ 256 = √ 2•2•2•2•2•2•2•2 =2•2•2•2•√ 1 =
± 16 • √ 1 =
± 16
x = ( 14 ± 16) / 6
x =(14+√256)/6=(7+8)/3= 5.000
and
x =(14-√256)/6=(7-8)/3= -0.333
x = -1/3 and x= 5

Answer 7

you are a goddess! I thank you!

Answer 8

I wouldn't go that far xD Anytime :)
