4x2 - 20 = 0
∴x2 - 5 = 0
∴x2 = 5
∴x = √5
X=1
Zero minus zero equals zero.
x = 5 / 6squared + 7
0 squared is 0. Zero times zero equals zero.
It Equals 2
zero
It equals 0. Zero times zero equals zero.
It can be solved by using the quadratic equation formula.
I'll assume that's - 5c. Then you're looking for numbers that multiply to -24 and add to -5. That's -8 and 3. (c - 8)(c + 3) = 0 c = 8, -3
Without that other number, all you've got is zero.
It is, as stated, 2x2 + x - 1 = 0. That is the quadratic form.
3x2 - 11x - 4 = 0(3x + 1)(x - 4)x = -1/3 and 4
