R2 - 16 = 0
R2 = 16
Take the square root of each side to get rid of the square on R.
R = 4
m2 - 8m + 16 = 0 (m - 4)2 = 0 so m = 4
The value of x is 7
2(x - 2)(x - 4)
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
4m2-256 = 0 Add 256 to both sides: 4m2 = 256 Divide both sides by 4: m2 = 64 Square root both sides to find the value of m: m = 8 Alternatively, if 4m is to be squared, and not just the m: (4m)2 - 256 = 0 16m2 - 256 = 0 16m2 -256 + 256 = 256 16m2 = 256 16m2/16 = 256/16 m2 = 16 √m2 = √16 m = ±4
x^(2)-16=0 Take the -16 over to the other side of the equal sign, the -16 will turn +16. x^(2)=16 Then take the squared root of both sides. x=4
m2 - 8m + 16 = 0 (m - 4)2 = 0 so m = 4
0 squared is 0. Zero times zero equals zero.
The value of x is 7
No, it equals 0. If you have nothing, and you multiply it by nothing, you still have nothing.
2(x - 2)(x - 4)
x^(2) - 10x + 16 = 0 Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'. Setting up brackets ( x 2)(x 8) Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative. Hence (x - 2)(x - 8 ) = 0 When x - 2 = 0 x = 2 & when x - 8 = 0 x = 8 So the two answers are ,2, & ,8, .
It equals 0. Zero times zero equals zero.
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
By factoring. q2 + 16q = 0 q (q + 16) = 0 Now, either q = 0, or q + 16 = 0. Solve those two equations to get the solution.
the answer of √8x+16-3x=0 is x= 0.447213595 = +/- 0.447(to 3 decimal places) if I'm not mistaken
