x2+3x = 7 x2+3x-7 = 0 Using the quadratic equation formula:- x = -4.541381265 or x = 1.541381265
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
3x - 7 = 2 3x = 9 x = 3
3X^2 + 7 = 2X subtract 2X from each side and in standard form 3X^2 - 2X + 7 = 0 Use discriminant b^2 - 4ac (-2)^2 - 4(3)(7) = 4 - 84 < 1 so, no real roots
