PLEASE HELP FAST Which of the following is a quadratic equation written in standard form?

5x−15=0

7x2−15=32x

8x2−10x=0

6x2=14−17x

Restrictions on f(x) = 1/x+5 and g(x) = x-2

Solve the following inequalities and show the solution on a number line. 2x+3< 3(4x+5)

Me! i will mark you brainliest if you are right and show your i don't get polynomials and all the other stuff. multiply and simplify.2x(^2)y(^3)z(^2) · 4xy(^4)x(^2)show your
