Preform the operation indicated (x^2+7x-9)-(3x^2-2x+11)

−2x^2 + 9x − 20

Step-by-step explanation:

distribute the negative to the expression and simplify

x^2 + 7x + −9 + −3x^2 + 2x + −11

= −2x^2 + 9x − 20

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
