There are no real solutions because the discriminant of the quadratic equation is less than zero.
What is 9x2 equals 10x plus 2?
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
Which best explains why the equation 7x plus 3 equals 7x plus 3 has infinitely many solutions?
Strictly speaking the above equation is a tautological equation or an IDENTITY. An identity is true for all values of any variables that appear in it. Thus, the above "equation" is true for all value of x. - that is, it has infinitely many solutions.
How many positive integer solutions does the equation 2x plus 3y equals 100 have?
This question cannot be answered because there are no operations defined, such as +, -, x, /, and = .
8y plus 4 equals -3x?
is an equation of a line in plane coordinate geometry. The coordinates of every point on that line satisfy the equation so there are an infinite number of solutions to the equation.
