How to find the discriminant of
Evgen [1.6K]

the discriminant   b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0


13x^2-16x = x^2 -x


we need to get in it the standard form


subtract x^2 from each side


12x^2 -16x = -x


add x to each side


12x^2 -15x = 0


12x^2 -15x -0 =0


a=12 b=-15 c=0


b^2 -4ac


the discriminant = b^2


b^2 = (-15)2 = 225

Two consecutive intergers have a sum of 79, find the intergers
aev [14]

Answer:

<em>The integers are 39 and 40.</em>

Step-by-step explanation:

Let the smaller integer be x.

The next greater integer is x + 1.

Their sum is x + x + 1.

Their sum is 79, so

x + x + 1 = 79

Solve for x.

2x + 1 = 79

2x = 78

x = 39

x + 1 = 40
