Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.

JulijaS [17]

Answer:

a) $b^2-4ac$

b) 25

Step-by-step explanation:

a) The quadratic formula is $x=\frac{-b\pm \sqrt{b^2-4ac} }{2a}$ .

The portion under the radical sign ( $b^2-4ac$ ) is called the discriminant or determinant.

It tells us that, the quadratic equation can be solved by factoring, if its value is a perfect square.

b) The given quadratic equation is $2x^2+7x+3=0$ .

By comparing to $ax^2+bx+c=0$ , we have a=2, b=7, and c=3

We substitute these values to get:

$b^2-4ac=7^2-4(2)(3)$

$b^2-4ac=49-24$

$b^2-4ac=25$
