Question

When 10x2 + x - 23 is divided by (2x +
3), the remainder is​

Answer 1

Step-by-step explanation:

when 10x²+x-23 divide by 2x+3 is equals to 5x-7

Answer 2

The remainder when the expression 10 x² + x - 23 is divided by  (2x + 3) is - 2.

Given: The expression 10 x² + x - 23 is divided by  (2x + 3).

To Find: The remainder when the expression 10 x² + x - 23 is divided by  (2x + 3).

Solution:

• To find the remainder when an expression is divided by another expression, we used the remainder theorem.
• We take a function f(x) of the expression and if it is divided by ( x - a ), then the remainder is f(a).

According to the sum,

        f(x) = 10 x² + x - 23  is divided by ( 2x + 3 ) or x = - 3/2

So putting x = - 3/2 in f(x), we shall get the remainder;

        f ( - 3/2 ) = 10 × ( - 3/2 )² + ( - 3/2 ) - 23

                       = ( 42 / 2 ) - 23

                       = - 2

Hence, the remainder when the expression 10 x² + x - 23 is divided by  (2x + 3) is - 2.
