Answer:
1) Solving the term using F.O.I.L we get
2) solving the term using F.O.I.L we get
3) Solving using square of binomial we get
4) Solving using square of binomial we get
Step-by-step explanation:
1) (3x + 5)(2x - 3). Solve using the F.O.I.L.
F.O.I.L stands for First, Outer Inner Last
We have
First: 3x(2x)
Outer: 3x(-3)
Inner: 5(2x)
Last: 5(-3)
Solving we get:
So, solving the term using F.O.I.L we get
2) (x + 2)(x – 13). Solve using the F.O.I.L.
F.O.I.L stands for First, Outer Inner Last
We have
First: x(x)
Outer: x(-13)
Inner: 2(x)
Last: 2(-13)
Solving we get:
So, solving the term using F.O.I.L we get
3) (x + 5)^2. Solve using the square of Binomial.
The square of binomial is:
Solving:
So, solving using square of binomial we get
4) (x -3)^2. Solve using the square of Binomial.
The square of binomial used is:
Solving:
So, solving using square of binomial we get
