This week we studied the relationship between the coefficient and roots of quadratic equations

It was easy to understand because the only thing that you must put only in your mind is "if x1 and x2 are the roots of the quadratic equation ax2 + bx = c = 0, then

x1 + x2 + -b/a and x1 x2 = c/a...

thank you..

"hi ma'am!"

I learned to get the discriminant of the equation. The formula for this is b=4ac.... I also learned to get the sor and por of the quadratic equation...

thnks...

Hi ma'am!

This week we discussed about the quadratic equation This equation is defined by the equation "ax + bx + c =0" We also studied the roots of a quadratic equation and solution of a quadratic equation vby factoring.. For me it is easy to learned if you'll study it very well..

"Hello ma'am!"

This week we studied the graphs of linear inequalities . It is easy to understand but sometimes I forget the rules. I am wrong in shading or the direction of the line.. That's all.. Thanks...
