What is the discriminate of the following quadratic equation?<br> 4x^2 - 2x + 6 = 0

hram777 [196]

-92

Step-by-step explanation:

If a quadratic equation has the following form:

$ax^2 + bx + c =0, \;\;\;a \neq 0$

then its discriminant D is defined as

$D = b^2 - 4ac$

In our given quadratic equation, a = 4, b = -2 and c = 6, so its discriminant is

$D = (-2)^2 - 4(4)(6) = -92$

Note: The value of the discriminant D will determine the characteristics of the roots of the quadratic equation according to the following rules:

$D > 0,\;\;$ there will be 2 real roots

$D = 0,\;\;$ there will be 1 real root

$D < 0,\;\;$ there will be 2 imaginary roots

Hence our given quadratic equation will not have any real roots but only imaginary ones.

Expand 2(m+5)+4(m-6)

Vlad1618 [11]

Answer:

$6m - 14$

Step-by-step explanation:

$2(m + 5) + 4(m - 6) \\ = 2m + 10 + 4(m - 6) \\ = 2m + 10 + 4m - 24 \\ = (2m + 4) + (10 - 24) \\ = 6m - 14$
