Answer 1

Answer:

1. ( c)

2. 0

3. 5

4. not defined

5. p(x) = x²-2√2 x +1

p(2√2) = (2√2)²-2√2 (2√2)+1

= 4×2-4×2+1

= 8-8+1

= 1

6. 5x-4x²+3 when x= -1

5(-1)-4(-1)²+3

-5-4+3

-9+3

-6

7. p(x) = x+3

p(x)+p(-x)

x+3+(-x)+3

x+3-x+3

3+3

6

8. not defined

9. -5/2

p(x) = 2x+5

p(-5/2) = 2(-5/2)+5

= -5+5

= 0

10. 1/2

2x²+7x-4 =0

2x²+8x-1x-4 =0

2x(x+4)-1(x+4) =0

(2x-1) (x+4)=0

2x-1=0 ; x+4=0

x=1/2. ; x=-4

hope it will help you dear ☺️☺️
