Answer 1

Answer:

-8x² -6x + 35

Step-by-step explanation:

A expression is given to us and we need to find out the quadratic equation . For that Multiply the two terms of the quadratic equation. The given expression is ,

Given expression :-

$\rm\implies ( 2x +5)( 7 - 4x )$

Multiply the terms :-

$\rm\implies 2x ( 7 - 4x )+5(7-4x)$

Simplifying the brackets :-

$\rm\implies 14x - 8x^2 + 35 - 20x$

Rearrange and simplify :-

$\rm\implies -8x^2 -6x + 35$

Therefore :-

$\rm\implies\boxed{ \rm Quadratic\ Equation \ = -8x^2 -6x + 35}$
