Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523
x2+10x+1 = -12+2x x2+10x-2x+1+12 = 0 x2+8x+13 = 0 Solving by using the quadratic equation formula: x = - 4 - or + the square root of 3
x2 - 10x - 6 = 2x + 1 Subtracting 2x + 1 from both sides gives: x2 - 12x - 7 = 0
x = - 4 - or + the square root of 3 Solved by using the quadratic equation formula.
x = 7/2 and also x = -3/2 by using the quadratic equation formula.
