Question

simplify 7x^2-2x+5

Answer 1

it has imaginary roots

Answer 2

the discriminant is less than zero...

Answer 3

at first it was 21x^4-6x^3+15x^2
which then became 3x^2(7x^2-2x+5)

Answer 4

roots are (2+136i)/14 , (2-136i)/14 and 0

Answer 5

i think im getting my signs mixed up on the next

Answer 6

huh?

Answer 7

i?

Answer 8

i comes for imaginary roots....if you are asked for real roots of the given equation, then your answer is just zero

Answer 9

are we talking about solving it? i only need to simplify ive gotten down so far 3x^2(_x__)(_x__)

Answer 10

like the reverse of foil method

Answer 11

3x^2(7x^2-2x+5) becomes zero when 3x^2=0 or 7x^2-2x+5=0....okay then, you cannot simplify it further

Answer 12

gotcha

Answer 13
