Converting from Standard to Factored Form Quadratics

Reorder the following steps for converting from standard to factored form.

• Keep a & c but replace with new b's.

• Find the GCF if there is one.

• Factor and then write your final answer with f(x)=.

• Multiply a & c.

• Find the factors that multiply to equal a & c but add to equal b.

Factored form of a quadratic function reveals the...

• roots

• axis of symmetry

• vertex

• whether the parabola is positive or negative

(7r-6)(7r+6)

• 49r²+36

• 49r²-36

• 49r²+84r+36

• 49r²+42r+36

Turn the following quadratic function from standard form into factored form:

y = x² - 10x + 25

• y= (x + 5) (x - 5)

• y = (x - 15) (x + 10)

• y = (x + 5) (x - 20)

• y = (x - 5) (x - 5)
