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)
Solve using the quadratic formula
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
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)
It equals 0. Zero times zero equals zero.
Solve using the quadratic formula
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
Any value multiplied to zero (0) always equal zero(0) So 16 X 0 = 0 1000000 x 0 = 0 0.0001 x 0 = 9 Philosophically, if there is 'nothing' (zero )0)), how can you apply/multiply it to anything.
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.
