Question

subtract the following equation​

Answer 1

Answer:

The expression after subtractions is $-2x^2+3x-1$

Step-by-step explanation:

The given expressions are,

$5x^2+x+9 \ \ \ \hspace{3cm} (1)\\\\7x^2-2x+10 \hspace{3cm} (2)$

Now we can subtract equation (2) from (1).

$5x^2+x+9-(7x^2-2x+10)=5x^2+x+9-7x^2+2x-10\\\\ \ \ = -2x^2+3x-1$

The result is  $-2x^2+3x-1$
