Quadratics with Leading Coefficient

Find two numbers that multiply to -40 and add to -6

• 1, -40

• 2, -20

• 4, -10

• 5, -8

Write a + or a - sign in each box so the expressions on each side of the equal sign are equivalent.

• +,+

• +,-

• -, +

• -, -

Match each quadratic expression in standard form with its equivalent expression in factored form.

• (x+5)(x+7)

• (x+5)(x-7)

• (x-5)(x+7)

• (x-5)(x-7)

Multiply (x+2)(x+2). You can double distribute or use the diagram we learned!
