Question

find x (3x-17) (8x+10)​

Answer 1

Answer:

Step-by-step explanation:

(3x-17)(8x+10)=180

We move all terms to the left:

(3x-17)(8x+10)-(180)=0

We multiply parentheses ..

(+24x^2+30x-136x-170)-180=0

We get rid of parentheses

24x^2+30x-136x-170-180=0

We add all the numbers together, and all the variables

24x^2-106x-350=0

a = 24; b = -106; c = -350;

Δ = b2-4ac

Δ = -1062-4·24·(-350)

Δ = 44836

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

x1=−b−Δ√2 ax2=−b+Δ√2 a

The end solution:

Δ−−√=44836−−−−−√=4∗11209−−−−−−−√=4√∗11209−−−−−√=211209−−−−−√

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-106)-2\sqrt{11209}}{2*24}=\frac{106-2\sqrt{11209}}{48}

$

$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-106)+2\sqrt{11209}}{2*24}=\frac{106+2\sqrt{11209}}{48}

$
