What method corresponds to use to solve equation?

x² + 6x + 20 = -3x

• Magic AC method

• GCF method

• UnFOIL or Short process method

• Perfect square trinomial method

Solve follwoing required steps:

x² + 6x + 20 = -3x

• x = -2, x = -10

• x = -3, x = -4

• x = -4, x = -5

• x = 4, x = 5

What should you do first in solving this equation?

x² + 6x - 13 = 3

• Get factored form

• Find two numbers which add to make 6 and multiply to make -13

• Make it equal 0

• Type it all in a calculator.

What method corresponds to use to solve the equation

x² + 6x + 9 = 0?

• Magic AC method

• Perfect square trinomial method

• GCF method

• UnFOIL or Short process method

Factor x² + 6x + 9 and solve for x. 

• (x+3)(x+3); x = -3
• (x+4)(x+5); x=-4, -5
• (x-3)(x-3); x=3
• Not factorable
