factor x squared + 10x

Question

having a bit trouble a explanation would be appreciated :]]

Answer 1

x ^2 + 10x + 0  pretty much you need a number that multiplies to 0, and adds up to a positive 10.

10 and 0,   10x0 = 0 and  10 + 0 = 10 these numbers satisfy both conditions.

(x - 10) (x + 0) is your answer

since we already know x = 10 and x =0

if we solve x - 10 = 0 we get positive 10 that is why it is x-10 and not x+10

(x - 10) (x + 0) is your answer
