Question

Quadratic equations that can be solved using the quadratic formula can also be solved by factoring.

Answer 1

true or false?

Answer 2

yes...........true.......but it will be diffcult as sometimes answers might be in irrational numbers, imaginary unit, decimals, .....

Answer 3

true

Answer 4

oops its actually
sometimes
always
never

Answer 5

always

Answer 6

sometimes

Answer 7

its called the box method

Answer 8

in what case, we cant solve HERO

Answer 9

I think joe math might be able to explain it better than I can

Answer 10

but, even equations with roots imaginary unit, fractions and decimals can be solved by factorization........difference is it will be time taking and harder

Answer 11

The answer the teacher wants is sometimes, but the actual answer is always. put sometimes though. If this is high school, most high school teachers dont consider things like:\[(x-\frac{1+\sqrt{5}}{2})(x-\frac{1-\sqrt{5}}{2})=x^2-x-1\] to be proper.

Answer 12

I was going to post a response similar to that

Answer 13

But the actual answer is a polynomial can always be factored in the complex numbers.

Answer 14

so, answer is always, isnt it

Answer 15

you can also use a graphing calculator by going into y= putting in quadratic equation pressing 2nd then trace(will come up as calc) go to zero answer three questions (left,right,guess) then u get your answer

Answer 16

I know that all polynomials are factorable, like joe said, it's the answer that the teacher wants that counts

Answer 17

yeah, im my experience with high school teachers ( in the US anyways), the answer is sometimes.

Answer 18

This is where edit button is needed. I meant to say all quadratics*

Answer 19

in*

Answer 20

I'm going to bed. It's getting very late. Bye everyone
