Verified answer

remember the formula

x=(-b +- √b^2 - 4ac) ÷ 2a

b is the second value of the equation with a single variable

a is the first value of the equation, where the variable is squared

c is the third value of the equation, also known as the constant term

replace all the variables to the numbers (NOTE: If the equation has no number before the variable like x^2, the x is always assumed as 1)

x= [(-2) +-√[2^2- 4(1)(10)]]÷ 2(1)

=[(-2)+- √[4- 40]] ÷ 2

=[(-2) +- √-36]]÷ 2

=[(-2) +-(6)] ÷ 2

=(-2-6) ÷ 2 OR (-2+4) ÷ 2

=(-8) ÷ 2 OR (-2) ÷ 2

x= -4 OR -1

Keep in mind, when solving with quadratic formula, there will always be two answers

you know, homework is so that you can practice, not so other people can do your homework for you. find the quadratic formula in your textbook and plug and chug numbers.
