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

Which equation can be rewritten as x + 4 = x2? Assume x greater-than 0 StartRoot x EndRoot + 2 = x StartRoot x + 2 EndRoot = x S
Mila [183]

We have been given an equation x+4=x^2. We are also told that x is greater than 0. We are asked to choose the equation that can be written as our given equation.

Since x is greater than, so we will take positive root on both sides of our given equation as:

\sqrt{x+4}=\sqrt{x^2}

\sqrt{x+4}=x

Upon looking at our given choices, we can see that option C is same as our answer.

Therefore, option C is the correct choice.
