Perfect Square Trinomials Quiz

Perfect Square Trinomials

• A perfect square trinomial takes the form ( (x + a)^2 ) or ( (x - a)^2 ), and expands to ( x^2 + 2ax + a^2 ).
• To form a perfect square trinomial, the middle term's coefficient must be double the square root of the last term.

Missing Numbers to Complete Perfect Square Trinomials

• For the expression ( x^2 + 6x + 9 ), the number is 9. It completes the equation as it equals ( (x + 3)^2 ).
• For ( x^2 + 10x + ___ ), the missing number is 25, completing the expression to ( (x + 5)^2 ).
• For ( x^2 + 8x + ___ ), the missing number is 16, forming ( (x + 4)^2 ).

Additional Notes

• To convert ( x^2 + 6x ) into a perfect square trinomial, the number 9 must be added, resulting in ( (x + 3)^2 ).
• The coefficient of ( x ) in the expression ( x^2 + 6x + 9 ) is 6, coming from the original term ( 2a ) where ( a = 3 ).
• The perfect square trinomial form of ( x^2 + 10x + 25 ) is ( (x + 5)^2 ).
