Answer:
t = 0, t = - 2
Step-by-step explanation:
Given
- t² - 2t = 0 ← factor out t from each term
t(- t - 2) = 0 ← in standard form
Equate each factor to zero and solve for t
t = 0
- t - 2 = 0 ( add 2 to both sides )
- t = 2 ( multiply both sides by - 1 )
t = - 2, thus
solutions are t= 0, t = - 2
Answer:
x =5
Step-by-step explanation:
transfer -2 to the other side it turns to +2
|2x-1|=7 +2
2x-1 =9
transfer -1 to the other side it turns to +1
2x=10
Divide both sides by 2
2x /2 = 10/2
x= 5
