Answer:
12.
a.
i. (x-9)(x-3)
ii. x = 9 or 3
b. (y+10(y-10)
Step-by-step explanation:
12.
a.
i.
Two numbers that multiply to make 27 and add to make -12 are: -9 and -3.
Put into brackets so you have: (x-9)(x-3)
ii.
Consider each bracket as its own equation.
x-9=0
x=9
x-3=0
x=3
b.
Difference of two squares
Answer:
Inverse of -5-9x/x-6
Step-by-step explanation:
Steps:
1: Interchange the variables x and y.
x=6y-5/y+9
2: Solve x = 6y-5/y+9 for y
3: Multiply both sides by y+9
4: Simplify and Expand
5: Subtract 9x from both sides.
6: Simplify and Subtract y from both sides then Simplify again
7: Divide both sides by x-6
Answer: Inverse of -5-9x/x-6
