Answer:
Simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .
Step-by-step explanation:
As the expression given in the question be as follow .
= (x−3)( x²−4x−7)
simplify the above
= x (x²-4x-7)-3 (x²-4x-7)
Now open the bracket
= x³ - 4x² -7x - 3x² + 12x + 21
= x³- 4x²-3x²-7x + 12x + 21
= x³ -7x² + 5x + 21
Thus the simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .
