How many root of a linear equation?
Answers
Answer:
Polynomials have as many roots as their degree. The degree is typically the highest power of the independent variable. (This is a little oversimplified, but we’re gonna roll with it.)
Step-by-step explanation:
A degree 2 polynomial (a quadratic) has 2 roots.
A linear equation in the form y = mx + b is degree 1, since this is x1 and has one root.
A linear equation in the form y = c is degree 0, since this is x0 and has zero roots.
For example, y=2x2+8x+6 is equivalent to y=2(x+1)(x+3) . When you set y=0 and solve, you get x=-1 and x=-3.
And y = 2x + 4 is equivalent to y = 2(x+2). When you set y=0 and solve, you get x=-2.
But y = 7 has no roots, because 0 = 7 is a contradiction.
