Question 808712

to evaluate the polynomial for {{{x=4}}} and for {{{x=-4}}}, substitute {{{x}}} with given value in

{{{2x^2-3x+7}}}

so, if {{{x=4}}} you will have:

{{{2(4)^2-3(4)+7}}}

={{{2*16-12+7}}}

={{{32-12+7}}}

={{{27}}}


and, if {{{x=-4}}} you will have:

{{{2(-4)^2-3(-4)+7}}}

={{{2*16+12+7}}}

={{{32+12+7}}}

={{{51}}}
