# Solving a system week 12

This week in Pre Calculus 11 I learned to solve a system by substituting one of the equations for (y) and solving for both (x) then (y)

# Week 11 Solving a Quadratic with a number line

This is week in Pre Calculus 11 I learned how to solve a quadratic inequality using a number

# Week 10 Finding (a)

This week in Pre Calculus 11 I learned how to find (a) by isolating it and solving the rest of the equation

# Week 9 (Finding the Zeros)

This week in Pre Calculus 11 I learned how to find the Zeros in a quadratic equation

the zeros are the X intercepts used to help complete a graph or solve a graph, they can help you a lot and are a important part to solving a quadratic equation

# Week 8 Complete the square for standard form

By using complete the square I am able to turn the quadratic equainto standard for or (Vertex Form)

thus creating and equation to solve for the vertex for a parabola

# Week 7 Finding discriminant

This is how to find the Discriminant by using the formula in the image and simply plugging the numbers in

so if x>0 we have two roots

if x=0 we have one root

if x<0 we have no roots
