Best ResponseYou've already chosen the best response.0Simplify (x+3)2 + 4x Evaluate : (x+3)2 = x2+6x+9 Factoring x2+10x+9 (x+9) • (x+1) (x + 9) • (x + 1) = 0 Solve (x+9)•(x+1) = 0 Solve : x+9 = 0 Subtract 9 from both sides of the equation : x = 9 Solve : x+1 = 0 Subtract 1 from both sides of the equation : x = 1

Best ResponseYou've already chosen the best response.1No. you're not moving anything across an equal sign. so there's no need to change the postive and negative. x^2 + 4x + 9

Best ResponseYou've already chosen the best response.1@Albany_Goon The question isn't asking us to find "x". It's asking us to rearrange the equation.

Best ResponseYou've already chosen the best response.1@zarkam21 No, not quite. you seem to have the 4x wrong. It should be \[x^2+4x+9 = 0\]
