Minus 61 (-61)
What is the solution set of 2x2 + x = 15
17x2-11x+2 = 2x2 Subtract 2x2 from both sides: 15x2-11x+2 = 0 Factorise: (3x-1)(5x-2) = 0 Solution: x =1/3 or x = 2/5
2x2-7x+3 = 0 (2x-1)(x-3) = 0 x = 1/2 or x = 3
Well im not a mathmatician but my guess is that 2X2-6X+24 doesn't equal anything so you cant solve for X that's my guess
2x2+5x-3 = 0 (2x-1)(x+3) = 0 x = 1/2 or x -3
Factors are (2x + 1)(x + 4), making x either -0.5 or -0.25
2x2 + 4 + 1 = 2x2 + 5 So, the vertex is (0, 5)
2x2 equals 5
Reading this as: 4x2-6=2x2 This implies that: -6=-2x2 3=x2 x=sqrt(3) and x=-sqrt(3) So x can equal plus or minus the square root of 3
2x2 + 3x + 1 = (x + 1)(2x + 1)
d/dx 2x2+3x+7=4x+3
2x2+13x+15 = (2x+3)(x+5)
