If this is an equation then write:
x-2=0
x=2
3x+3=0
x=-1
so smaller solution is x= -1 and larger is x=2
Two minuses = Plus.
Therefore, it is 8--7.
Answer:
Cube
Step-by-step explanation:
The cubed root of 8 = 2 because 2³ = 8.
So 8 is perfect cube.
Answer:
1 + sin2x
Step-by-step explanation:
Given
(sinx + cosx)² ← expand using FOIL
= sin²x + 2sinxcosx + cos²x
[ sin²x + cos²x = 1 and sin2x = 2sinxcosx ]
= 1 + sin2x
