F(x) = (x + 1)(x - 2)
f(x) = x(x - 2) + 1(x - 2)
f(x) = x(x) - x(2) + 1(x) - 1(2)
f(x) = x² - 2x + x - 2
f(x) = x² - x - 2
Answer:
Option (2)
Step-by-step explanation:
Given expression is, AX + B = C



AX + B = C
AX = C - B
C - B =
= 
C - B = 
Let 
AX =
= 
Since AX = C - B

Therefore, a = 1, b = 5
(-3a - 4c) = -35
3(1) + 4c = 35
3 + 4c = 35
4c = 32
c = 8
And (-3b - 4d) = -11
3(5) + 4d = 11
4d = -4
d = -1
Therefore, Option (2). X =
will be the answer.
Answer:
51,51 and 78
Step-by-step explanation:
3x+9=4x-5
3x=4x-14
-x=-14
x=14
(b^2+5)(−b^2+7)
Use the FOIL METHOD to expand.
