Question

14. Represent (x-2)(3x + 5) = 2x (x-4) is a form of quadratic equation​

Answer 1

$\textbf{Concept:}$

$\text{An equation of the form ax^2+bx+c=0 is called}\;\textbf{Quadratic equation}$

$\textbf{Given:}$

$(x-2)(3x+5)=2x(x-4)$

$\text{Using term by term multiplication}$

$3x^2+5x-6x-10=2x^2-8x$

$3x^2-x-10=2x^2-8x$

$3x^2-2x^2-x+8x-10=0$

$x^2+7x-10=0$

$\therefore\textbf{Quadratic form of given equation is \bf\,x^2+7x-10=0 }$

b) 2x^2– x + 3 = 0 

c) 2x^2+ 9x + 13 = 0

d) 2x^2 + x + 3 = 0​
