a perfect square trinomial has a factor that is identical to the other factor. In this case, from the first term, the factor is composed of 2x while from the third term, there is a term 7 involved. In this case, the factor is 2x + 7. so the second term has to be 2*(2*7) equal to 28

<span>The usual price of a toy was $64. a shop sold the toy to customers at $72. find the percentage increase in price.
Answer: Work out the difference between the new number and the old one.
72 - 64 = 8
Then you divide the increase by the original number.
8/ 64 = 0.125.
Then multiply by 100.
0.125 x 100 = 12.5
Therefore the percentage increase is 12.5%
Hope This Helps You!
