If x squared equals n, then x is the square root of n.
x=9 squared
(x + 7)2 = 5 x + 7 = ±√5 x + 7 - 7 = -7 ± √5 x = -7 ± √5
x-10=15 Add 10 to both sides x=25
X squared = x+6 6+x=x squared X=6
X (x - 25) So X = 0 Or X = +25
32 + x = 259 + x = 25x = 25 - 9x = 16
-5x2 = -75 x2 = 25 x = ±sqrt( 25 ) x = ±___
x = 25 / 3squared + 5
x2 = -25 There exists no real number for which this is true, so we must use imaginary numbers... x = 5i
"x squared equals to 25" is not an inequality! You need to re-think the question!
Rearrange: x2 - 10x + 25 = 0ie (x - 5)(x - 5) = 0x = 5Check: x2 = 25; 10x - 25 = 50 - 25 = 25. Job done
Solve this problem -x squared -40x- 80 =0
find out what 6 squared equals. which is 6 x 6 and that equals 36
If x squared -10 = 0 then x = the square root of 10
(x-3)(x+2)the answer is x=3
(x-5)(x+3)
