Answer:
this is form =ax²+Bx+c
a=5,b=2,c =-2
x= -b±√b²-4ac quadratic formula
x= -(-2)±√-(2)²-4(1)-(-2) / 2×1
x= 2±√ 4+8 = 2± √12/2 = 2± 2√3/2 =
2 (1 ± √3) /2. = 1 + √3
x= 1+√3 and 1 - √3 are the roots of the quadratic equation m²= 2+2m
this is the right answer
Step-by-step explanation:

the answer is 7
[tex]at \: \: \: \: x = 2 \: \: \: \: the \: \: value \: \: of \: \: p(x) \: \: is \: \: 7[/tex]
[tex]p(x) = 2 {x}^{2} - 3x + 5 \\ [/tex]
[tex]p(2) = 2 \times {2}^{2} - 3 \times 2 + 5[/tex]
[tex]p(2) = 8 - 6 + 5[/tex]
[tex]p(2) = 7[/tex]
hence, value of the polynomial for x=2 is 7
