solutions? and x-intercepts?

lgbasallote · Answer

solution -> solve for x

x-int _> just same

.sam. · Answer

use quadratic formula

anonymous · Answer

You kinda have to use the quadratic formula.
$$-b ±\sqrt{b ^{2} - 4ac}\over2a$$

anonymous · Answer

I know I have to use the quadratic formula........the problem is using the formula

anonymous · Answer

What do you mean?

anonymous · Answer

I am not sure how?

anonymous · Answer

a = 3 b =-7 and c = -5   You will get a complex answer.

anonymous · Answer

a = 3
b = -7
c = -5
Just plug in numbers. The form for a quadratic is ax^2 + bx + c
That's where it comes in.

Do you understand?

anonymous · Answer

Im not sure how to calc x

anonymous · Answer

Your x will equal the complex number you get when you solve the quadratic equation..that is the x you are solving for.... x = quadratic equation.

??

anonymous · Answer

the x-intrecepts how do I write those?

anonymous · Answer

a = 3
b = -7
c = -5
(7 ±√109)/6
You can approximate it if you want, but these are the solutions. Last line.
