Can (5z+3)(-5z-3) result in a difference of squares

Mathematics
1 answer:
castortr0y [4]3 years ago
8 0

Answer:

no, it cannot

Step-by-step explanation:

a difference of square is: a² - b² = (a - b)(a + b)

looking at the expression (5z+3)(-5z-3), we see that it does not fit the criteria of the breakdown of a perfect square, as (-5z-3) has a negative <em>a</em> term (-5z)

if we FOILed (5z+3)(-5z-3) out, we would get:

-25z² - 30z - 9, which is not a difference of squares

Irina-Kira [14]

Answer:

x = -6       x=5

Step-by-step explanation:

x^2 +x -30 =0

Factor

What two numbers multiply to -30 and add to 1

6 * -5 = -30

6-5 =1

(x+6) (x-5) =0

Using the zero product property

x+6 =0    x-5=0

x+6-6=0-6    x-5+5=0+5

x = -6       x=5
