Answer:
Step-by-step explanation:
2x² + 5x + 2=0 (roots or zeros)
(2x+1)(x+2)=0
2x+1=0 ⇒ x=-1/2 or -0.5
x+2=0 ⇒ x=-2
<h2>(-0.5,-1/2)</h2>
x² - 4x + 3=0
(x-3)(x-1)=0
x-3=0 ⇒ x=3
x-1=0 ⇒ x=1
<h2>(3,1)</h2>
Is that the top or bottom? Assuming it's the top, when distributing the -2 to what's inside the parenthesis, they were correct in multiplying -2•7, but when they multiplied -2 and -y, the answer needs to be positive 2y because they are multiplying double negatives
3x * 3x = 9x
9x + 6 - 2x + 5x - 4x^2 + 9
9x + 6 - 7x - 4x * 4x + 9
9x + 6 - 7x - 16x + 9
9x + -7x = 2x + 6 - 16x + 9
2x + 6 - 16x + 9
2x + (-3) - 16x
-14x + (-3) is the expression?
Answer:
No
Step-by-step explanation:
its not because x doesn't go into all 3 coffecients (numbers) and 6 doesn't go into 3.
You can think of it like this:
D E F
Between D and E there are 27 units, between E and F there are 34 units so 27+34 is equal to the distance between D and F.
27+34=61
Hope this helps :)
