Question

(x − 3)(2x +1) = x(x + 5)

Check weather is using quadratic equation​

Answer 1

Answer:

Step-by-step explanation:

→ (x-3)(2x+1) = x(x+5)

→ x × 2x + x × 1 - 3 × 2x - 3 × 1 = x × x + x × 5

→ 2x² + x - 6x - 3 = x² + 5x

→ 2x²  - 5x - 3 = x² + 5x

→ 2x² - x² - 5x - 5x - 3

→ x² - 10x - 3

Answer 2

Answer:

(x − 3)(2x +1) = x(x + 5)

$2x^{2} +x-6x-3 = x^{2} +5x$

$x^{2} -10x-3=0$

x=(10±root(100+12))/2

SO IT IS SOLVABLE BY QUADRATIC FORMULA  METHOD

AND THE SOLUTIONS ARE

x = 5±8√7
