Finite Math. Find f (g (x)) f (x)=4x-1 , g (x)=x^2+1. f (x) = 4x − 1 f ( x) = 4 x - 1 , g(x) = x2 + 1 g ( x) = x 2 + 1. Set up the composite result function. f (g(x)) f ( g ( x)) Evaluate f (x2 +1) f ( x 2 + 1) by substituting in the value of g g into f f. f (x2 +1) = 4(x2 + 1)−1 f ( x 2 + 1) = 4 ( x 2 + 1) - 1. Simplify each term. Did you know that polynomials can be simplified by combining like terms? In the given polynomial, we can simplify it to -2x^2 + x + 3. Combining the x^2 terms (-3x^2 and -4x^2) gives us -7x^2 and combining the x terms (5x and -4x) gives us x. The constants (-2 and 5) stay the same. So the simplified form of the polynomial is -2x^2 + x + 3. lim -) x→-00 5x3+1 b. lim х-0о 10х3-Зx2+7 5x2+2 С. lim x→∞ Vx2+3 A: Limits of function can be found by simplifying the function and substituting values for x as given… Q: Find the limit, if it exists. What is the difference when 5x2 − 3x + 2 is subtracted from 4x2 − 7x + 9? A) x2 − 4x + 7 B) −x2 − 4x + 7 (3x3 - 4x2 + x - 2) - (x3 - 5x2 + 3x + 2) A Elementary Algebra. by Laura Bracken (0th Edition) Edit edition Solutions for Chapter 5 Problem 15T: Simplify.(5x2 + 7x − 18) + (3x2 − 4x − 2) … Solutions for problems in chapter 5 1RE Final answer: To simplify the expression, we subtract the second polynomial from the first by changing the signs of the terms in the second polynomial and combining like terms to get the final expression -x^2 + 12x - 5.

Explanation: Solving using Bhaskara: 2−4± 42 −4(1(−32)) 4x2+4x-3=0 Two solutions were found : x = -3/2 = -1.500 x = 1/2 = 0.500 Step by step solution : Step 1 :Equation at the end of step 1 : (22x2 + 4x) - 3 = 0 Step 2 :Trying to factor by 3.2 Solving 5x2-7x-1 = 0 by Completing The Square . Divide both sides of the equation by 5 to have 1 as the coefficient of the first term : x2- (7/5)x- (1/5) = 0. Add 1/5 to both side of the equation : x2- (7/5)x = 1/5. Now the clever bit: Take the coefficient of x , which is 7/5 , divide by two, giving 7/10 , and finally square it giving 49/100. Transcript. Example 4 Solve 5x – 2 (2x – 7) = 2 (3x – 1) + 7/( 2)5x − 2 (2x − 7) = 2 (3x − 1) + 7/2 5x − 4x + 14 = 2 (3x − 1) + 7/2 5x − 4x + 14 Multiply the new quotient term by the divisor. The expression needs to be subtracted from the dividend, so change all the signs in 4x3 +8x2 4 x 3 + 8 x 2. After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend. Pull the next terms from the original dividend down into the current dividend.
