Simplify the expression
x2a−2x−a2x+2a−7xa+14
Evaluate
(x−a−7)(xa−2)
Apply the distributive property
x×xa−x×2−axa−(−a×2)−7xa−(−7×2)
Multiply the terms
x2a−x×2−axa−(−a×2)−7xa−(−7×2)
Use the commutative property to reorder the terms
x2a−2x−axa−(−a×2)−7xa−(−7×2)
Multiply the terms
x2a−2x−a2x−(−a×2)−7xa−(−7×2)
Use the commutative property to reorder the terms
x2a−2x−a2x−(−2a)−7xa−(−7×2)
Multiply the numbers
x2a−2x−a2x−(−2a)−7xa−(−14)
Solution
