The rational expression 2(x-1)(4x+1) is option A one restrictions on x.
What is a rational expression?
Rational expressions appear like fractions that have variables of their denominators (and frequently numerators too). for example, three, quit fraction is a rational expression.
explanation:
The rational expression
2(x-1)(4x+1) = 0
4x^2 +1x -4x -1
4x^2 -3x -1 =0
4x^2 + x -4x -1 =0
x(4x+1) -1(4x + 1)=0
x-1=0 & 4x + 1 = 0
x =1 & x= - 1/4.
one is restricted on X .
Rational expressions are fractions that have a polynomial within the numerator, denominator, or each. despite the fact that rational expressions can seem complex because they incorporate variables, they may be simplified in the equal way that numeric fractions, also known as numerical fractions, are simplified.
A rational expression is considered simplified if the numerator and denominator have no factors in the commonplace.
For a rational expression in the lowest phrases, we should first locate all common factors (constants, variables, or polynomials) or the numerator and the denominator. accordingly, we must issue the numerator and the denominator. once the numerator and the denominator have been factored, pass out any commonplace elements.
