factor:
x squared +14x+49
Answered by drwls
It's a perfect square of (x + _)^2

See if you can fill in the blank
Answered by Henry
Factor:X^2 + 14X + 49. 49 = 1*49 = 7*7
Try 1 and 49 in your factored equation:
( X + 1 )*(X + 49). The product of the two binomials does not equal the original equation, Therefore, 1 and 49 is incorrect. Try 7 and 7:(X+7)*(X+7)=
X^2 + 14X +49. Yes!

Problem:(X+ )^2. The results will be a perfect square regardless of what number you put in the blank, because you remove the parenthesis by squaring the contents.(X+2)^2=X^2+4X+4.(X+3)^2=X^2+6X+9.Both trinominals are perfect squares.
