Question

(2x+5) or (4x-3 ka गूणफल gyat kijiye
​

Answer 1

Proper Question :-

• Find the product of the polynomials given below :

$\qquad\quad {:}\longmapsto \tt(2x+5) and (4x-3)$

Solution:-

First write the polynomial

$\qquad\quad {:}\longmapsto\tt (2x+5)(4x-3)$

• Let's use distributive law :

$\boxed{\bf (a+b)(c+d)=a (c+d)+b (c+d)}$

• Substitute the values :

$\qquad\quad {:}\longmapsto\tt 2x (4x-3)+5 (4x-3)$

• Now simplify :

$\qquad\quad {:}\longmapsto\tt 8x^2-6x+20x-15$

• Add or subtract accordingly ,

$\qquad\quad {:}\longmapsto\underline{\boxed{\bf{\pink{ 8x^2+14x-15}}}}$
