What are the steps for factoring a quadratic equation?

• Divide left and right terms in diamond by a, and simplify.

• Write left and right terms in factored form (x+_)(x+_). place a term in front.

• Distribute a term to set of parentheses with fraction inside.

• Multiply a & c, write in top of diamond. Put b in bottom.

• Determine factors of top that add to equal bottom, write these on left and right of diamond

Factor
4n²-17n-15

• (n-10)(6n+1)

• (4n-5)(n-3)

• (n-5)(4n-3)

• (n-5)(4n+3)

Factor the polynomial:
5x² - 13x + 6

• (x + 3)(5x - 2)

• (x - 2)(5x - 3)

• (x + 2)(5x + 3)

• (x - 3)(5x + 2)

Multiply:

(4a + 5 )( 5a - 7 )

• 20a - 35

• 20a + 35

• 20a² - 3a - 35

• 20a² + 3a - 35
