Best ResponseYou've already chosen the best response.1first factor out of x, can you do that for me?

Best ResponseYou've already chosen the best response.1x ( 4x^2 + 43x + 30 ) ?

Best ResponseYou've already chosen the best response.1now, lets focus on just the 4x²+43x+30

Best ResponseYou've already chosen the best response.1you know that if you choose (2x )(2x ) that is not going to give an odd coefficient 43 in a middle term, therefore you have to choose (4x )(x )

Best ResponseYou've already chosen the best response.1and you know that you have (4x + 1)(x + ) (2 pluses, because your trinomial is positive entirely)

Best ResponseYou've already chosen the best response.1now you have to choose two constant factors of 30 to fill it in.

Best ResponseYou've already chosen the best response.1The factors are 1, 2, 3, 5, 6, 10, 15, 30

Best ResponseYou've already chosen the best response.1yes, possible picks 1 & 30 2 & 15 3 & 10 5 & 6

Best ResponseYou've already chosen the best response.14x²+43x+30 (4x + )(x + )

Best ResponseYou've already chosen the best response.1The rule it that a+b=43 and ab=30?

Best ResponseYou've already chosen the best response.1im not entirely sure

Best ResponseYou've already chosen the best response.130×1=30, but 30 & 1 don't make the a+b=43

Best ResponseYou've already chosen the best response.1`(4)a+(1)b=43` and `ab=30`

Best ResponseYou've already chosen the best response.1you multiply on of the numbers by 4 and the other by 1 (multiplying by coefficients of x, just as you would if you were to expand it)

Best ResponseYou've already chosen the best response.14x²+43x+30 (4x + )(x + ) fill it for me please...

Best ResponseYou've already chosen the best response.1wait, this would give a middle term of (10 • x) + (4x • 3) = 10x+12x=22x

Best ResponseYou've already chosen the best response.1the other way around

Best ResponseYou've already chosen the best response.1so (4x + 3)(x + 10) ?

Best ResponseYou've already chosen the best response.1(4x•10)+(x•3)=40x+3x=43x

Best ResponseYou've already chosen the best response.14x³ + 43x² + 30x x ( 4x² + 43x + 30 ) x (4x + 3)(x + 10)

Best ResponseYou've already chosen the best response.1` x (4x + 3)(x + 10) ` is it.... you can't factor it more. DONE
