2 | (x+3)(x+5) = x2+8x+15 |
3 | (x+7)(x+1) = x2+8x+7 |
4 | (x+9)(x+4) = x2+13x+36 |
5 | (x+5)(x+7) = x2+12x+35 |
6 | (x+6)(x+2) = x2+8x+12 |
7 | (x−4)(x−5) = x2−9x+20 |
8 | (x−2)(x−9) = x2−11x+18 |
9 | (x+7)(x−4) = x2+3x−28 |
10 | (x−1)(x+3) = x2+2x−3 |
11 | (x+2)(x−8) = x2−6x−16 |
12 | (x−6)(x+5) = x2−x−30 |
13 | (x−4)(x+1) = x2−3x−4 |
14 | (x+3)(x−9) = x2−6x−27 |
15 | (a+5)(a−1) = a2+4a−5 |
16 | (y−4)(y+2) = y2−2y−8 |
17 | (b+4)(b+7) = b2+11b+28 |
18 | (n−3)(n+2) = n2−n−6 |
19 | (x+)(x+) = x2+x+ |
20 | (x+0.4)(x−0.3) = x2+0.1x−0.12 |
