Question

Write the expression (4x-2)•6(2x+ 7) in the ax2+bx+c What are the values of the coefficient

Answer 1

The values of the coefficient are ax^2+bx+c=

48x^2-24x+84 and A= 48, B=-24, C=84.

(4x-2)•6(2x+7)=

6•2x+ 6•7

(4x-2)(12x+42)=

4x•12x= 48x^2 4x•42= 168.

-2•12x= -24x -2•42=-84

48x^2-24x+168-84=

48x^2-24x+84=

A= 48, B=-24, C=84

ax^2+bx+c= 48x^2-24x+84.
