Which values are solutions to the inequality x2 equals 16?
x2 = 16take the root square for both sides the result will be :X = +4 or -4
How do you solve x2 equals 16?
If you meant x2 = 16 then take square root both sides which gives x = 4 but you need to see that -42 is also 16 so that is another solution. The two solutions are 4 and -4.
How many solutions to x2-10 equals 0?
x2-10 = 0 x2 = 10 x = the square root of 10
What are the solutions in completing the square x2 plus 6x equals 7?
x2 + 6x = 7 ⇒ x2 + 6x + 9 = 7 + 9 ⇒ (x + 3)2 = 16 ⇒ x + 3 = ±4 ⇒ x = -7 or 1
What are the solutions for the quadratic equation x2 plus 6x equals 16?
x2 + 6x = 16=> x2 + 6x - 16 = 0=> x2 + 8x -2x - 16 = 0=> (x+8)(x-2) = 0=> x = -8 or x = 2So, the solutions of the quadratic equation x2 + 6x = 16 are -8 and 2.
