Weegy: x= -4,1
User: 6x2 + 1 = 13
User: 6x ^2 + 1 = 13
Weegy: Simplify 6x^2+13+6. Reorder the terms: 13+6+6x^2. Combine like terms: 13+6=19. The final result is: 19+6x^2.
User: 3x2 + 2 = 11 - x2
User: 8x2 - 24 = 3x2 - 9
User: x2 = 144
Weegy: x^2=16; x=4, -4.
User: (x + 3)(x - 3) = 16 - 2x2
Weegy: The solution set of 2x2-3x=5 is either 3.5 or -.5, depending on context of question.
User: 5x2 - 55 = 90
User: 5x ^2 - 55 = 90
Weegy: This equation factors to (3x+2)(2x-3)
User: (2x - 1)(3x + 2) = x + 292
Weegy: x = 27/4
User: 7x2 = 49
