Question

3x^2+13x-10

Answer 1

= 0? Use the quadratic formula: \[ x_{1/2} = \frac{-b \pm \sqrt{ b^2 - 4ac }} {2a} \]

Answer 2

a = 3, b = 13 and c = -10.

Answer 3

no

Answer 4

Then, what is it? Factor it out? :-)

Answer 5

yes factoring

Answer 6

try (x+5) (3x- ??)

Answer 7

You can use the formula to find a root for the equation. Suppose the root is x = 5. Then, (x+5) will divide with no remainder the original polynomial. It can be rewritten as (x+5)(3x - 2) :-)

Answer 8

well i thought it wouls be this 3(x^2- - )

Answer 9

would

Answer 10

Neither 10 nor 13 is divisible by 3. That's not a common factor to it.

Answer 11

are* divisible

Answer 12

i kno
