Question

What is the quadratic equation 2x2+3x-20=0

Answer 1

3x=20+2x2=24
x=24÷3=8

Answer 2

The solution of quadratic equation are,

⇒ x = - 4

⇒ x = 5/2

We have to given that;

Quadratic equation is,

⇒ 2x² + 3x - 20 = 0

Now, We can simplify for the solution of equation as;

⇒ 2x² + 3x - 20 = 0

⇒ 2x² + 8x - 5x - 20 = 0

⇒ 2x (x + 4) - 5 (x + 4) = 0

⇒ (x + 4) (2x - 5) = 0

This gives,

⇒ x = - 4

⇒ 2x - 5 = 0

⇒ 2x = 5

⇒ x = 5/2

Hence, The solution of quadratic equation are,

⇒ x = - 4

⇒ x = 5/2
