7x+3=10x-9(shift +3 & 10x) 7x-10x=-9-3(signs changed) -3x=-12(divide both sides by -3) x=4

x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3

x2 + 10x + 21 = (x + 3)(x + 7)

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

x=3
