Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
No.
X= (3/5 , -2)
x = 2 or x = 2/5
5x2 - 136 = 44 5x2 - 136 + 136 = 44 + 136 5x2 = 180 5x2/5 = 180/5 x2 = 36 √x2 = √36 x = ±6
5x2-136 = 24 5x2 = 24+136 5x2 = 160 x2 = 32 x = the square root of 32
The discriminant is 385.
Yes
Same as log(5x2) = log(10).
There is no single coefficient for that equation, as a coefficient is the number by which any term is multiplied. The coefficients in that equation are 5, 2, 4 and 3.
It is: (5x-1)(x-1) = 0 Therefore: x = 1/5 or x = 1 Use the quadratic equation formula
x = -6 or 65x2 - 136 = 445x2 = 180x2 = 36
5x2 + 9x + 13 has no real factors.
