Question

x (2x + 5) = 3 solve this quadratic equations l​

Answer 1

Answer:

x(2x+5)=3

2x^2+5x-3=0

2x^2-x+6x-3=0

x(2x-1)+3(2x-1)=0

(x+3) (2x-1)=0

x=-3

x=1/2

Answer 2

Answer:

Given equation,

→ x(2x + 5) = 3

We have to find out the roots of this equation.

To do this, we will write the given equation in standard form and then factorise it by splitting the middle term. After factorisation, we will find out the zeroes by zero-product rule.

So,

→ x(2x + 5) = 3

→ 2x² + 5x - 3 = 0

Splitting the middle term,..

→ 2x² + 6x - x - 3 = 0

→ 2x(x + 3) - 1(x + 3) = 0

→ (2x - 1)(x + 3) = 0

→ (2x - 1) = 0 or (x + 3) = 0

→ x = 1/2, -3

So, the values of x are ½ and -3.

Answer:

• x = ½, -3.
