Subtract. (5x2−3x−2)−(−2x2−x+10) Express the answer in standard form. Enter your answer in the box.
Nimfa-mama [501]

Answer:

7x^{2}-2x-12=0

Step-by-step explanation:

we know that

The standard form of the quadratic equation is equal to ax^{2} +bx+c=0

we have

(5x^{2}-3x-2)-(-2x^{2}-x+10)

eliminate the parenthesis

5x^{2}-3x-2+2x^{2}+x-10

group terms that contain the same variable

(5x^{2}+2x^{2})+(-3x+x)+(-2-10)

combine like terms

7x^{2}-2x-12=0
