Resolve the quadratic trinomials into factors:3x2 + 22x + 35 |
|
Answer» We have, 3x2 + 22x + 35 The coefficient of x2 is 3 The coefficient of x is 22 Constant term is 35 So, we express the middle term 22x as 15x + 7x 3x2 + 22x + 35 = 3x2 + 15x + 7x + 35 = 3x (x + 5) + 7 (x + 5) = (3x + 7) (x+ 5) |
