Question

find the value of polynomials 5 x minus 4 x square + 3 at first x is equal to zero second x is equal to minus one third x is equal to 2 ​

Answer 1

Step-by-step explanation:

x at 0,

-4x²+5x+3= -4(0)²+5(0)+3=0+0+3=3.

x at 1/3,

-4x²+5x+3= - 4(1/3)²+5(1/3)+3=4/9+15/9+27/9(lcm)=46/9.

x at 2,

-4x²+5x+3= - 4(2)²+5(2)+3=16+10+3=29.
