What are the solutions to the quadratic equation 5x2 + 60x = 0?
x = 0 and x = −12
x = 0 and x = 12
x = 5 and x = −12
x = 5 and x = 12

Best ResponseYou've already chosen the best response.3factor out the like terms for \[5x^2+60x=0\]

Best ResponseYou've already chosen the best response.0Aren't I supposed to find what 5^2 and 60 have in common or something like that or I am mistaken ._.

Best ResponseYou've already chosen the best response.3yeah.... you are supposed to find what they have in common and yank em out.

Best ResponseYou've already chosen the best response.2Well in order to get 0 on the right we know that x=0 in one case because substituting 0 in we will get 0 on the left

Best ResponseYou've already chosen the best response.2To find the second number you have to factor out what you can so what can you factor out?

Best ResponseYou've already chosen the best response.3let's split this up for a sec \[5x^2+(5)(12)x=0\] ok what number do they have in common and what variable do they have in common?

Best ResponseYou've already chosen the best response.0They have 5 and 12 in common.... 5 and 12 have..... 3 in common I guess.... since 3 times 3 is 12 and 3 +2 = 5

Best ResponseYou've already chosen the best response.2They both have 5x in common so you can factor that out

Best ResponseYou've already chosen the best response.2So 5x(x+12)=0

Best ResponseYou've already chosen the best response.2To get the inside the brackets equal to 0 how do you get that?

Best ResponseYou've already chosen the best response.3well 12 x 5 = 60. when I split it up we have a 5 for the number in common and x for the variable in common so 5x gets yanked out and we're left with 5x(x+12)=0 now we solve for x for these two cases 5x = 0 and x +12 = 0

Best ResponseYou've already chosen the best response.2(X+12)=0 you want some number to be negative so it equals 0

UsukiDoll

Best ResponseYou've already chosen the best response.3we want x by itself for x+12=0 so we subtract both sides by 12

anonymous

Best ResponseYou've already chosen the best response.0The answer is still zero since 0 minus 12 is 12 and 12 divided by 0 is ZERO so both answers are Zero :D

Best ResponseYou've already chosen the best response.3there are two solutions of x.

UsukiDoll

Best ResponseYou've already chosen the best response.3we got x = 0 for 5x=0 now solve x+12 = 0 by subtracting 12 on both sides.
