Simplify the expression
k−ak+1
Evaluate
2k−2(k−1)a−k+1+(k−2)a
Multiply the terms
2k−2a(k−1)−k+1+(k−2)a
Multiply the terms
2k−2a(k−1)−k+1+a(k−2)
Expand the expression
More Steps
Calculate
−2a(k−1)
Apply the distributive property
−2ak−(−2a×1)
Any expression multiplied by 1 remains the same
−2ak−(−2a)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
