Factor the following polynomial completely. -0.8x2 - 6.4x + 7.2
Answers
Answer:
-0.8(x + 9)(x - 1)
Step-by-step explanation:
Note that 0.8 is a factor of the three coefficients -0.8, -6.4 and 7.2. Thus,
-0.8x2 - 6.4x + 7.2 = 0.8(-1x^2 - 8x + 9), or, equivalently,
= -0.8(x^2 + 8x - 9), which factors further as follows:
= -0.8(x + 9)(x - 1)

Step-by-step explanation:
choose two point of A, let k(-2, -3) and l(1, 3)
[tex] m = \frac{ - 3 - 3}{ - 2 - 1} = \frac{ - 6}{ - 3} = \frac{1}{2} [/tex]
choose two point of B, let c(0, 5) and d(5, 0)
