find out what 6 squared equals. which is 6 x 6 and that equals 36
X=1
since y = 3x+1 we have y squared =(3x+1) squared x^2 + y^2 = 25 x^2 + (3x+1)^2=25 x^2 + 9x^2+ 6x+1 = 25 10x^2 + 6x + 1 = 25 10x^2 + 6x -24 = 0 solve x from quadratic formula x = 1.28 y = 3x + 1 = 4.83
0
Using the quadratic equation formula: x = 8.42 or x = -1.42
5.
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
"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)
