Hi Classmate. I will factor your trinomial area into two binomials. x2 + 153-: + 26 square feet First, there is no greatest common factor to simplify the trinomial. I noticed that the leading coefcient is 1 {1x2}. So, I can look for pairs of factors that when multiplied = 26. {1){25} = 25 (4)145} = 26 {2){13} = 26 {en-13} = 25 The magic combo is the pair that when added equal the middle coefcient. Which pairs add up to 15? 1+ 26 = 2? 1 + 26 = 27 2 + 13 = 15 -2 + -13 = -15 I will use the magic combo in the binomial format (x+ _](x + _J. The factored form is then x"- + 153:: + 25 = lx+ 21lx+ 13] I will choose a square with area, A= S2. The length of my bed will be 4 feet and then I will add a walkway of an unknown dimension, x. The total length is (x+4). The width will also be 4 feet with an unknown dimension of x. The total width is (x+4). Length= x+4 Width = x+4 To find the area of square, I need to calculate A=$2. Area =(x+4)(x+4) I can FOIL this to get: First=x*x=a2. Inner= 4*x=4x Outer=4*x=4x Last=4*4=16 My final answer is: a2+8x+16 square feet. A picture of square garden.do...
