Question

can you factor 3x^2 + 4x - 5

Answer 1

can the factors of 15 make 4?

Answer 2

(3x + a)(x + b)

Can you solve the system:
3b + a = 4
ab = -5

Answer 3

Its (x+1)(9x-5)

Answer 4

^no its not

Answer 5

@ello_bello That expands to 9x² + 4x -5. Close, but no

Answer 6

@DDCamp that gives you fraction and decimals...the polynomial cannot be completely factored only this:\[x(3x+4)-5\]

Answer 7

can't be factored

Answer 8

I just used an online calculator. http://www.freemathhelp.com/factoring-calculator.php

Answer 9

ello, the calculator probably assumed your input was (3x)², which is 9x²

Answer 10

oh yeah probably.
