i get really confused of how to factor 5c^2 - 24c - 5 ?
i mean i know how to factor a polynomial with a degree of 2 but when the X ^ 2 has a coefficient like 5 i get really mixed up.... also i don't wanna do quadratic formula cuz it takes so much time....

COEFF of c^2 = +5
( +5) ( -5) = -25
FIND FACTORS OF -25 WHICH ADD up to - 24 ( COEFF of c)
( -25) ( +1) = -25
5c^2 -25c +c -5
5c ( c - 5) + 1( c-5)
( 5c +1) ( c-5) ANSWER
( +5) ( -5) = -25

5c^2 -25c +c -5
5c ( c - 5) + 1( c-5)
( 5c +1) ( c-5) ANSWER

(5c+1)(c-5)
