Answer:
Step-by-step explanation:
No solution because the variable canceled it’s self
By using completing the Square method ,
-x^2-2x+6
= - ( x^2+2x-6) -> factorise -1
= - ( ( x+1 )^2 - (1)^2 -6 ) -> complete the square
= - ( x+1 )^2 +7
- ( x+1 )^2 =0 -> equip it to 0
-x-1 =0
X = -1
axis of symmetry : x = -1
well lets say i have to subtract 34 and 20 which is 14 so i would take the sum and the subtractor which is 20 the i would do 20 plus 14 which is 34
Hope this helps!
Step-by-step explanation:
5(x + 7) = 15
x+7=3
x=-4!!!!!!
