Help me please!! This is timed and I’m stuck

zhuklara [117]

Let's solve

$\\ \sf\longmapsto 2x^2+7x-15=0$

$\\ \sf\longmapsto x=\dfrac{-7\pm\sqrt{7^2-4(2)(-15)}}{2(2)}$

$\\ \sf\longmapsto x=\dfrac{-7\pm\sqrt{169}}{4}$

$\\ \sf\longmapsto x=\dfrac{-7\pm13}{4}$

$\\ \sf\longmapsto x=\dfrac{-7+13}{4}\:or \:\dfrac{-7-13}{4}$

$\\ \sf\longmapsto x=\dfrac{6}{4}\:or\:\dfrac{-20}{4}$

$\\ \sf\longmapsto x=\dfrac{3}{2}\:or -5$

Subtract

$\\ \sf\longmapsto 3/2-(-5)=3/2+5=13/2$

Option B

Let f(x)=3x-6 and g(x)=x-2. Find the value of f/g and its domain

Ket [755]

F(x) = 3x - 6
g(x) = x - 2

$\frac{f(x)}{g(x)}= \frac{3x-6}{x-2} \\ \\ 
= \frac{3(x-2)}{x-2} \\ \\ 
=3$

This means the value of the ratio f(x)/g(x) will be equal to 3.

Domain of the fraction is Set of All real numbers except 2. At 2 the given fraction will be undefined as the denominator in the very first fraction will be zero. Another reason 2 is not a part of the domain is that it will make x-2 equal to zero and we cannot cancel out 0 with 0 from numerator and denominator.

In interval notation, the domain will be: (-∞,2)∪(-2 ,∞)
