The zeros are the points on the x-axis where the graph intersects.
For factorization, you do (x - the zero) for each zero, and multiply them together.
7. A. The zeros are -2 and 4.
The factorization is (x + 2)(x - 4)
7 B. The zeros are 1 and 3.
The factorization is (x - 1)(x - 3)
Answer:
that's not quadratic formula or square method
Step-by-step explanation:
i personally thing the quadratic formula is easier which is
x = -b+-√b^2 -4ac
----------------------------
2a
you just plug in a b and c into the equation which is
x^2 is a which is 1
-6x is b which is -6
1 is c and its just 1
the answer also needs to involve a radical which for example 3√2
Answer:
19

Answer:
20
Step-by-step explanation:
(-4) × (-5) = 20
Hope this helps
-4x + 9y = 9...............(1)
x - 3y = -6 Multiply through by 3:-
3x - 9y = -18..............(2)
adding equations (1) and (3):-
-x = -9
x = 9
Substitute for x in equation (1)
-4(9) + 9y = 9
-36 + 9y = 9
9y = 45
y = 5
Answer is x = 9 and y = 5
