Solve (4x square-3x+7)-(xsquare+ 8x-5) |
|
Answer» Step-by-step explanation:Simplifying (4x2 + 3x + 7)(8X + -5) = 0 Reorder the terms: (7 + 3x + 4x2)(8x + -5) = 0 Reorder the terms: (7 + 3x + 4x2)(-5 + 8x) = 0 MULTIPLY (7 + 3x + 4x2) * (-5 + 8x) (7(-5 + 8x) + 3x * (-5 + 8x) + 4x2 * (-5 + 8x)) = 0 ((-5 * 7 + 8x * 7) + 3x * (-5 + 8x) + 4x2 * (-5 + 8x)) = 0 ((-35 + 56x) + 3x * (-5 + 8x) + 4x2 * (-5 + 8x)) = 0 (-35 + 56x + (-5 * 3x + 8x * 3x) + 4x2 * (-5 + 8x)) = 0 (-35 + 56x + (-15x + 24x2) + 4x2 * (-5 + 8x)) = 0 (-35 + 56x + -15x + 24x2 + (-5 * 4x2 + 8x * 4x2)) = 0 (-35 + 56x + -15x + 24x2 + (-20X2 + 32x3)) = 0 COMBINE like terms: 56x + -15x = 41x (-35 + 41x + 24x2 + -20x2 + 32x3) = 0 Combine like terms: 24x2 + -20x2 = 4x2 (-35 + 41x + 4x2 + 32x3) = 0 Solving -35 + 41x + 4x2 + 32x3 = 0 Solving for variable 'x'. The solution to this equation COULD not be determined. |
