Question
Solve the system of equations
t=0
Evaluate
{t×1=1×t21×t2=21t×1
Calculate
{t=t21×t2=21t×1
Calculate
More Steps

Evaluate
t=t2
Move the expression to the left side
t−t2=0
Factor the expression
More Steps

Evaluate
t−t2
Rewrite the expression
t−t×t
Factor out t from the expression
t(1−t)
t(1−t)=0
When the product of factors equals 0,at least one factor is 0
t=01−t=0
Solve the equation for t
More Steps

Evaluate
1−t=0
Move the constant to the right-hand side and change its sign
−t=0−1
Removing 0 doesn't change the value,so remove it from the expression
−t=−1
Change the signs on both sides of the equation
t=1
t=0t=1
Calculate
t=0∪t=1
{t=0∪t=11×t2=21t×1
Calculate
{t=0∪t=1t2=21t
Calculate

Evaluate
t2=21t
Move the expression to the left side
t2−21t=0
Factor the expression
More Steps

Evaluate
t2−21t
Rewrite the expression
21t×2t−21t
Factor out 21t from the expression
21t(2t−1)
21t(2t−1)=0
When the product of factors equals 0,at least one factor is 0
21t=02t−1=0
Solve the equation for t
t=02t−1=0
Solve the equation for t
More Steps

Evaluate
2t−1=0
Move the constant to the right-hand side and change its sign
2t=0+1
Removing 0 doesn't change the value,so remove it from the expression
2t=1
Divide both sides
22t=21
Divide the numbers
t=21
t=0t=21
Calculate
t=0∪t=21
{t=0∪t=1t=0∪t=21
Find the intersection
