(x - 4) • (x + 5) = 0 Step 2 : Theory - Roots of a product : 2.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. We shall now solve each term = 0 separately In other words, we are going to solve as many equations as there are terms in the product

Sal determines how many solutions the equation x²+14x+49=0 has by -4x^2+( 41/2)x-5/2 = 0 and from this equation you see that -4x^2+(41/2)x-5/2 is yet  Phân tích thành nhân tử : a. x^2 - 4x - 5 = 0. b. 2x^2 - 6x + 4 = 0. c.

What values could we substitute for x to make this expression equal 0? If we had x = -1, the left binomial would simplify to 0, and multiplying (x-5) times 0 makes 0. Similarly, if x = 5, the same thing would happen. So your answer is that x = -1 or +5.
