X-4x-5 = 0

To use the direct factoring method, the equation must be in the form x^2+Bx+C=0. r + s = -4 rs = -5 Let r and s be the factors for the quadratic equation such that x^2+Bx+C=(x−r)(x−s) where sum of factors (r+s)=−B and the product of factors rs = C

This inequality could be solved very easily doing algebra, but it makes a good graphical example. First we sketch a graph of y = 2x + 3 as shown in Figure 8. Note that it is a straight line. It has a slope of 2 and an intercept on the y axis of 3. 1. Let f(x)= -5x-1 and?g(x)=x2+ 5. Find (f * g)(1).

Note que para o numerador e denominador terem o mesmo sinal é porque todas as Solve x2- 4x - 5 = 0. A very full explanation would be: Start by listing the pairs of numbers that can be multiplied together to get 1 * -5 = -5 (i.e.

For math, science, nutrition, history Jul 28, 2015 · First observe that the sum of the coefficients is 0, so x=1 is a root. Then divide by (x-1) to get a quadratic that is easier to factor and thus solve to find two other roots x=3 and x=-2. Let f(x) = x^3-2x^2-5x+6 First note that the sum of the coefficients is 0, so x=1 is a zero of f(x) f(1) = 1-2-5+6 = 0 Divide f(x) by (x-1) to find: f(x) = x^3-2x^2-5x+6 = (x-1)(x^2-x-6) Then x^2-x-6 = (x 2 The solution to x – 4x – 5 ≥ 0 is (−∞,−1]∪[5,∞) Note 1: When we are using test points we are only interested in the sign of the answer (is it positive or negative) and so we could find this out by using the factored form of the quadratic. Answer to: Solve: 5(-3x - 2) - (x - 3) = -4(4x + 5) + 13. By signing up, you'll get thousands of step-by-step solutions to your homework questions.
