The point-slope form:
- slope
- point
We have the point and the slope
Substitute:
Please help! Find the zeros of the quadratic equation by factoring. x^2-25=0
1 answer:
Answer:
x=-5, 5
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. This is a difference of squares. Factor by taking the square root of each term.
Once you have the factors, set them equal to 0 and solve for x to find the zeros.
(x+5)=0
x=-5
(x-5) = 0
x=5

Answer:
The solution is obtained by adding the two equations.
The solution is: (x, y) = (,
)
Step-by-step explanation:
We are given two equations with two variables. The strategy is to eliminate one variable and solve for both the variables.
The two equations are:
Adding both the equations, we get:
Substituting the value of 'x', we get the value of y.
We substitute in (2). [Can be substituted in any equation].
We get: y = 2x - 1
So, we get the corresponding values of x and y which is the solution of the two equations.
