Please help me write quadratic equation given the roots and the leading coefficient
Pie

Answer:

Example Question: f(x) = 2x^2 + 2x - 1


If the leading coefficient is positive, the graph will be opening up (U) if the leading coefficient is negative, the graph will be opening down (n)


Roots are the x-intercepts that help find the axis of symmetry (add the two roots together and divide the result by 2 to get the axis of symmetry)


To find the vertex, simply imput the axis of symmetry into the given equation.


And that’s about it.

Step-by-step explanation:

I don’t know what you’re asking for??

In a class, 42 students, there are 8 more boys than girls write and solve a system of 3 equations
zhenek [66]

Answer:

x = 17

Step-by-step explanation:

x + x + 8 = 42     because x = boys and x + 8 = girls

2x = 34      because 2x = 42 - 8

x = 17            



i hope this helps!  you don't need the 2x = 42 - 8 to be an equation      ;)
