Step-by-step explanation:
3/4 + (-2 1/2)
3/4 - 2
-1 3/4
Be more specific for yssss !!
Let's rewrite the expression as

So, if
, you may divide both sides by
, the equation becomes
, and the only solution is
, which means that this is not an identity (an indentity is tautologically true, no matter the value of x).
If instead
, you are multiplying both sides by zero, so the equation becomes

So, it doesn't matter which value for x you choose, because you will always end up with
, which is obviously always true.
<h3>I'll teach you how to solve 15x ^2 −4x−4</h3>
--------------------------------------------------------
15x ^2 −4x−4
Break the expressions into groups:
(15x^2+6x) + (-10x-4)
Factor out 3x from 15x^2+6x:
3x(5x+2)
Factor out -2 from -10x-4:
-2(5x+2)
3x(5x+2) -2(5x+2)
Factor out common term 5x+2:
(5x+2)(3x-2)
Your Answer Is (5x+2)(3x-2)
