Write a quadratic equation in standard form that has two solutions, 1 and -6 ___?_=0 (the leading coefficent must be 1 )

OpenStudy (anonymous):

if those are the solutions, can you write the expression in factored form? {Where and how do the solutions show up in the factored form of a quadratic?}

OpenStudy (anonymous):

I'm not really sure how to do that?

OpenStudy (anonymous):

factored form is like (x + ___)(x + ___) =0 remember?

OpenStudy (anonymous):

so it would be x+6 and x+1 right

OpenStudy (anonymous):

what usually goes in the blanks?

OpenStudy (anonymous):

(x+6)(x-1) =0

OpenStudy (anonymous):

I'm confused sorry.

OpenStudy (anonymous):

they give you the solutions. Remember what 'solution' means: it's the value of x that makes an equation true.... if one of the solutions is -6 does putting -6 in for x make the expression I just showed you true?

OpenStudy (anonymous):

yes?

OpenStudy (anonymous):

right.

OpenStudy (anonymous):

so do you agree that (x+6)(x-1) =0 is the factored form of the quadratic with solutions of -6 and 1?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

the computer said that was wrong??

OpenStudy (anonymous):

it's the factored form, expand it to get the standard form.

OpenStudy (anonymous):

so would the answer be x^2+5x+6??

OpenStudy (anonymous):

yep
