If plx), 6x²+5x²-3x+2 find
p(1) p(-2) p(-3)​

Answer 1

Answer:

direct giving

step-by-step explanation ok??

Step-by-step explanation:

(i) 4x2 – 3x + 7

⇒ 4x2 – 3x + 7x°

∵ All the exponents of x are whole numbers.

∴ 4x2 – 3x + 7 is a polynomial in one variable.

(ii)

∵ All the exponents of y are whole numbers.

∴ is a polynomial in one variable.

(v) x10 + y3 + t50

∵; Exponent of every variable is a whole number,

∴ x10 + y3 + t50 is a polynomial in x, y and t, i.e. in three variables.

Answer 2

Step by step verification :

p(x) = 6x2 + 5x2 - 3x + 2

p(1) = 6 x (1)2 + 5 x (1)2 - 3 x 1 + 2

= 6 + 5 - 3 + 2

= 13 - 3

= 10

p(-2) = 6 x (-2)2 + 5 x (-2)2 - 3 x -2 + 2

= 6 x 4 + 5 x 4 - 3 x -2 + 2

= 24 + 20 + 6 + 2

= 52

p(-3) = 6 x (-3)2 + 5 x (-3)2 - 3 x (-3) + 2

= 6 x 9 + 5 x 9 - 3 x - 3 + 2

= 54 + 45 + 9 + 2

= 110
