6x²-7x=20 solve the following quadratic equation

anyanavicka [17]

Answer:

x = -4/3 and x = 5/2.

Step-by-step explanation:

6x² - 7x = 20

6x² - 7x - 20 = 0

To solve this, we can use the quadratic formula to solve this.

[please ignore the A-hat; that is a bug]

$\frac{-b±\sqrt{b^2 - 4ac} }{2a}$

In this case, a = 6, b = -7, and c = -20.

$\frac{-(-7)±\sqrt{(-7)^2 - 4 * 6 * (-20)} }{2(6)}$

= $\frac{7±\sqrt{49 + 80 * 6} }{12}$

= $\frac{7±\sqrt{49 + 480} }{12}$

= $\frac{7±\sqrt{529} }{12}$

= $\frac{7±23 }{12}$

$\frac{7 - 23 }{12}$ = $\frac{-16 }{12}$ = -8 / 6 = -4 / 3

$\frac{7 + 23 }{12}$ = $\frac{30}{12}$ = 15 / 6 = 5 / 2

So, x = -4/3 and x = 5/2.

Hope this helps!
