Question

5x²-3x=45 then find x
​

Answer 1

Required Answer:-

Given:

• 5x² - 3x = 45

To find:

• The roots of the given equation.

Solution:

We have,

➡ 5x² - 3x = 45

➡ 5x² - 3x - 45 = 0

Now, its in the standard form.

Here,

• a = 5
• b = -3
• c = -45

So,

x = (-b ± √(b² - 4ac))/2a

= (3 ± √(9 - 4 × 5 × (-45)))/10

= (3 ± √(9 + 900))/10

= (3 ±√{9(1 + 100)})/10

= (3 ±3√101)/10

Hence, the roots of the given Quadratic Equation are (3 + 3√101)/10 and (3 - 3√101)/10

Answer:

• The roots of the given Quadratic Equation are (3 + 3√101)/10 and (3 - 3√101)/10
