Question

HELP PLEASE!!!
I need two numbers that multiply to give you -20 and add up to give you -5.
factoring trinomials

Answer 1

can you write your original equation something doesn't fit

Answer 2

whats the coefficient of x^2

Answer 3

because I think you need to solve using general quadratic formula...or completing the square

Answer 4

a^2-5a-20

Answer 5

and its factoring trinomials

Answer 6

\[a^2-5a-20\]

Answer 7

yup

Answer 8

the factors of -20 are 1 x 20, 2 x 10 or 4 x 5

you can't get five from the factors with the the larger factor being negative...

Answer 9

pretty sure @campbell_st is correct using the general quadratic formula otherwise like he just said its "not possible".

Answer 10

then the problem is prime

Answer 11

using the general quadratic formula the will give you factors of\[x = \frac{5 + \sqrt{105}}{2} ======== and===== x = \frac{5 - \sqrt{105}}{2}\]

Answer 12

im in 9th grade this is algebra 1

Answer 13
