Question

Multiply (x²-3) (2x-7x³+4) and write the degree of the product. Write the correct alternative answer for each of the following questions.
(A) 5
(B) 3
(C) 2
(D) 0

Answer 1

hiii!!!

here's Ur Answer...

given :- (x²-3)(2x-7x³+4)

= x²(2x-7x³+4) - 3(2x-7x³+4)

= 2x^3 - 7x^5 + 4x^2 - 6x + 7x^3 - 12

the correct option is (a)5 as it is the highest power of the terms given in the polynomial.

hope this helps..!!

Answer 2

Solution :

(x²-3)(2x-7x³+4)

=x²(2x-7x³+4)-3(2x-7x³+4)

= 2x³-7x^5+4x²-6x+21x³-12

= -7x^5+23x³+4x²-12

Therefore ,

Degree of the product = highest power

of x in the product

= 5
