Simplify 15(x - 4)(x -1)-3(x + 4)(x - 1) with steps

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.

Can some one explain this i got sent this. is this a threat i’m scared
