 Question 95435: =+ What is B? I tried the following approach: 7=A*(x+9)+B* 7=x*(A+Bx)+9A+5B 7=9A+5B & x(A+Bx)=0 I could only say B=(7-9A)/5 & either x=0 or x=-A/B I'm not sure how to move from here to the next in order to find the solution. Could you help? The question was given by teacher on the board, not from a textbook. Click here to see answer by stanbon(57387)

 Question 95517: Hello! I have tried to work this problem out but my answer doesn't appear to work when I plug it back in. I must be doing something wrong. Solve the following equations algebraically: (x+7)*(x-1)=(x+1)^2 Here is my work: I foiled both of the sides to come up with: x^2+7x-1x-7=x^2+2x+1 I brought over the right side to give me: 4x=-6 x=-3/2 I could be doing this totally wrong. Any help will be greatly appreciated. Click here to see answer by edjones(7569)

 Question 98979: My problem is written as; I had to name the property in each step. The first step they switched the x, so I think it's symmetric. step 2, the x came to be on the outsid and I'm thinking that's reflexive. I need help on these steps bcause they are confusing. x(y+1)+(-1)x = x(y+1)+x(-1) = x [(y+1)]+(-1)] = x[y+(1+ (-1))] = x [y+0] = xy Click here to see answer by stanbon(57387)
