Question

If the polynomial
${3x}^{2} + {kx}^{2} + 2k - 3$
Leaves a remainder 5 when divided by x-2 find the value of k. Is x+1 is a factor of this polynomial ​

Answer 1

Answer:

Ans. (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
