4x2 - 20 = 0
∴x2 - 5 = 0
∴x2 = 5
∴x = √5
X=1
x = 5 / 6squared + 7
Zero minus zero equals zero.
0 squared is 0. Zero times zero equals zero.
It Equals 2
zero
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
It can be solved by using the quadratic equation formula.
It equals 0. Zero times zero equals zero.
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
