Question

Subtract.

Answer 1

(x^2+3x−7)−(3x^2−5x+3)

x^2-3x^2 +3x -(-5x) -7-3

x^2(1-3) +x(3+5) -(7+3)

-2x^2+ 8x-10

Answer 2

Answer:

$-2x^2+8x-10$

Step-by-step explanation:

Like terms are those which have same variable to the same power.

Standard form of any quadratic equation is in the form of:

$y=Ax^2+Bx+C$

To subtract :

$(x^2+3x-7)-(3x^2-5x+3)$

Remove the parenthesis;

$x^2+3x-7-3x^2+5x-3$

Combine like terms;

$-2x^2+8x-10$

Therefore, the answer in standard form is, $-2x^2+8x-10$
