What value for "c" makes the quadratic a perfect square trinomial?
Q. Alright, so I was absent on the day that this was explained in Algebra 1, and I don't understand how to find this answer (we don't have books, just binders to take notes in, thus no section explaining this) What value for "c" makes the quadratic a perfect square trinomial? x2+32x+c I'd like it if you could explain how to get the answer.

A. Think that (a + b)^2 = a^2 + 2ab + b^2 Then, a = 1 2ab = 32 then b = 16 So, c = 256

A. Take half of 5 or 5/2 and square it. (5/2)^2=25/4 To prove it (x+5/2)^2=x^2+5x/2+5x/2+2 5/4=x^2+5x+25/4 All you have to do is divide the B term by 2 and square it to find C in the form y=Ax^2+Bx+C On an easier example if you had x^2+6x+C It would be (x+3)^2 which equals x^2+6x+9 See that C=9 which is (6/2)^2 or 3^2 Note: The first answer posted is incorrect.

A real-life tutor who can talk to you and show you in person is best, but I'm going to try to help you understand. a polynomial is in the form ax^2 + bx + c. This is from the formula of (Z*x + q) * (R*x + p). Don't let all these letters scare you. They are just place holders for numbers. The only thing that can get the letter A in Ax^2 +bx +c is the first two parts of the "terms" you need to multiply together. With letters a= z*r. In order to get C, you only need to worry about the last parts in the terms. Using letters c= q*p. B is what makes sure you know what two terms… [cont.]

Asked by Ash - Mon Aug 27 19:01:51 2007 - - 1 Answers - 0 Comments
A. Hi, A polynomial is a perfect square trinomial if: 1) there are 3 terms 2) the first and third terms are positive perfect squares, like 4x or + 25y Determine what terms you would multiply together to get the first and third terms. For 4x and 25y , you would square 2x and 5y. 3) the center term equals either plus or minus twice the product of these 2 terms. So the center could be + 20xy or - 20xy. For 36a - 84ab + 49b , you would square 6a to get the first term and would square 7b to get the third term. If you multiply 2 times 6a times 7b, this gives 84ab. If the center term is either + 84ab or - 84ab, then this is a perfect square trinomial. 36a - 84ab + 49b factors into (6a - 7b)(6a - 7b). I hope that helps!! :-)
