Find the zeros of the following polynomial x^2-2x+1

muminat

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.

What is the solution of the system? Use any method.<br><br> 3x + 2y = 7<br> y = –3x + 11

Gnom [1K]

Answer:

$(5,-4)$

Step-by-step explanation:

SOLVE BY SUBSTITUTION:

STEP 1: Replace all occurrences of $y$ with $-3x+11$ in each equation.

$-3x+22=7\\y=-3x+11$

STEP 2: Solve for $x$ in the first equation.

$x=5\\y=-3x+11$

STEP 3: Replace all occurrences of $x$ with $5$ in each equation.

$y=-4\\x=5$

the polygons in each pair are similar. find the scale factor of the smaller figure to larger figure.

katovenus [111]

Answer:

Scale factor = $\frac{1}{2}$

Step-by-step explanation:

From the picture given in the question,

If the larger figure is dilated to form the smaller figure,

Scale factor by which a figure is dilated with is determined by the expression,

Scale factor = $\frac{\text{Measure of one side of the smaller figure}}{\text{Measure of the corresponding side of the larger figure}}$

= $\frac{3}{6}$

= $\frac{1}{2}$
