Answer 1

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

Answer 2

Answer:

the answer is 7

Step-by-step explanation:

$at \: \: \: \: x = 2 \: \: \: \: the \: \: value \: \: of \: \: p(x) \: \: is \: \: 7$

$p(x) = 2 {x}^{2} - 3x + 5$

$p(2) = 2 \times {2}^{2} - 3 \times 2 + 5$

$p(2) = 8 - 6 + 5$

$p(2) = 7$

hence, value of the polynomial for x=2 is 7
