The quadratic equation has 2 real solutions

<em>Greetings from Brasil....</em>

Let's solve this 2nd degree equation.

6b² + 8b - 10 = 0       dividing all terms by 2

3b² + 4b - 5 = 0         applying the baskara formula

Δ = 4² - 4 · 3 · (- 5)

Δ = 76

b = (- 4 ± √76)/6      so

<h2>b' = (- 4 + √76)/6</h2><h2>b'' = (- 4 - √76)/6</h2>

Did I do this right ?

No you did not

If original function is y= 3x-2 than inverse function is

3x=y+2 => x= (y+2)/3  than when we change the roles

we get inverse function y=(x+2)/3

Good luck!!!

Right angled triangle calc: find a, b=24, c=33.94113
Ksenya-84 [330]
Use the Pythagorean theorem...
a²+b²=c², in this case a²=c²-b<span>²</span>

a²+24²=33.94113<span>²

a</span><span>²+576=1,152.00031

a</span><span>²=576.000306

a=24    (If you need the exact number, not rounded, it is 24.0000064)</span>
