2x2 + 4 + 1 = 2x2 + 5 So, the vertex is (0, 5)
d/dx 2x2+3x+7=4x+3
2x2+13x+15 = (2x+3)(x+5)
2x2 + 11x + 15 = (x + 3)(2x + 5).
2x2 + 15x + 25 = (2x + 5)(x + 5)
2x2 + 4 + 1 = 2x2 + 5 So, the vertex is (0, 5)
2x2 equals 5
2x2 + 3x + 1 = (x + 1)(2x + 1)
d/dx 2x2+3x+7=4x+3
2x2+13x+15 = (2x+3)(x+5)
8 - 2x2 = x + 22 - 7Combine like terms on the right side:8 - 2x2 = x + 15Subtract 8 from each side:-2x2 = x + 7Add 2x2 to each side:0 = 2x2 + x + 7
2x2 + 11x + 15 = (x + 3)(2x + 5).
2x2 + 15x + 25 = (2x + 5)(x + 5)
