2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
4x3+10x2+2x+5= (2x+5)(2x2+1)
Divide all terms by 2 and when factored it is: (x+1)(x+1)
2x2 + 4 + 1 = 2x2 + 5 So, the vertex is (0, 5)
Factors are (2x + 1)(x + 4), making x either -0.5 or -0.25
(2x + 1)(x + 3) are the factors.
2x2 - 5x + 12 does not factor. 2x2 - 5x - 12 factors into (2x + 3)(x - 4) 2x2 + 5x - 12 factors into (2x - 3)(x + 4)
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
4x3+10x2+2x+5= (2x+5)(2x2+1)
Divide all terms by 2 and when factored it is: (x+1)(x+1)
2x2 + 4 + 1 = 2x2 + 5 So, the vertex is (0, 5)
2x2 equals 5
Factors are (2x + 1)(x + 4), making x either -0.5 or -0.25
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
