Use the x-intercept method to find all real solutions of the equation.
x^2-9x^2+23x+15=0

b.

Step-by-step explanation:

The given equation is;

To solve by the x-intercept method we need to graph the corresponding function using a graphing tool.

The corresponding function is

The solution to is where the graph touches the x-axis.

We can see from the graph  that; the x-intercepts are;

(1,0),(3,0) and (5,0).

Therefore the real solutions are:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
