Example: evaluate the function f(x) = 2x+4 for x=5. Example: evaluate the function h(x) = x 2 + 2 for x = −3. Replace the variable "x" with "−3": h(−3) = (−3) 2 + 2 = 9 + 2 = 11. Without the you could make a mistake: h(−3) = −3 2 + 2 = −9 + 2 = −7 (WRONG!) Also be careful of this:
Factor 2x^3-x^2-5x-2. Step 1. Factor using the rational roots test. Tap for more steps Step 1.1. If a polynomial function has integer coefficients, then every rational zero will have the form where is a factor of the constant and is a factor of the leading coefficient. Step 1.2. Similar Problems from Web Search. 2x2-x-3=0 Two solutions were found : x = -1 x = 3/2 = 1.500 Step by step solution : Step 1 :Equation at the end of step 1 : (2x2 - x) - 3 = 0 Step 2 :Trying to factor by splitting the 2x (2)=19x+33 Two solutions were found : x = -3/2 = -1.500 x = 11 Rearrange: Rearrange the equation by subtracting what is A "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x = −1/2. (You can also see this on the graph) We can also solve Quadratic Polynomials using basic algebra (read that page for an explanation). 2. By experience, or simply guesswork.Example \(\PageIndex{5}\) Divide: \(\frac{25x^{2}-5x+10}{5}. Solution:. First, treat this as \(\frac{1}{5}\) times the expression in the numerator and then distribute.MfuR.
