If the polynomial is of the form x^2+bx+c (ie., no factor in front of the x^2!!) then you can look for numbers that add up to b and multiply to c.
So in this case: what two numbers, when added, give -2 and when multiplied, give 1? A little trial and error gives you -1 and -1.
So the factorization is (x-1)(x-1). This is zero for x=1. There is only one zero.
Answer:
D. x = 2
Step-by-step explanation:
You multiply the numbers
4X0.55= 2.2
but since you need that 0.2 to complete the self you round up to 3 <span />
