Directions: Find the roots of the following quadratic equations using the quadratic formula.

1. x²-4x+4=0
2. x²-3x+2=0
3. 4x²+6x+9=0
4. x²+9x+2=0

1. Are all the equations in standard form?

2. Did you easily get the roots for each quadratic equation?

3. What can you say about the roots of each quadratic equation?​

1. x²-4x+4

(x-2)(x-2)

roots = 2 and 2

2. x²-3x+2

(x-2)(x-1)

roots = 2 and 1

3. 4x²+6x+9

( parang namali mo ito ng pagtipa sa 2nd term which is 12x dapat)

no real roots

4. x²+9x+2

(parang namali mo ito ng pagtipa sa 3rd term which is 20 dapat)

no real roots
