**1. **Case 1: figure A

Case 2: figure D

Case 3: figure B

Case 4: figure C

**b**.(x+a)(x+b)=x^{2}+ax+bx+ab

** **=x^{2} + (a+b)x + ab

**C.1**.(x+0)(x+b)=x^{2} +0+bx+0

**2**.(x+a)(x+0)=x^{2}+ax+0+0

**3**.(x+0)(x+0)=x^{2}+0+0+0

** **

**2.a**.(50+2)(50+7) = 2500+(9)(50)+14

= 2500+450+14

=2950+14

=2964

**b.(**10+6)(10+3)=100+(9)(10)+18

=100+90+18

=190+18

=208

**c.(40+8)(40+2)****=1600+(10)(40)+16**

**=1600+400+16**

**=2000+16**

**=2016**

>>>How did you do this? Explain.>>>

**b.63X67=4221**

**c.81X89=7209**

**d.95X95=9025**

Can you explain more here? Maybe the question would help or writing complete sentences...

e.10

**f.(b)4 (c)8 (d)0**

**g.(b)n=4 a=3 b=7**

**(c)n=8 a=1 b=9**

**(d)n=0 a=5 b=5**

**h.what?**

**i.what?**

**j.multiply each other**

**k. I learned to do a lot of stuff in this question on what to do to get the answer.**

** **

**4.(a)**x^{2}

** (b)(x+4)(x+4) =****x^2+4x+4x+16 **(use the pattern)

** =X^2+8x+16**

** **

**a=x^2 b=8x a+b=X^2+8x **(not sure what you are saying here)

** **

**(c)much greater. under the 4x and beside the 4x.**

**(d)more larger**

**(e)what?**

**??? **

**5.(a)91204**

**(b)2916**

**(c)4225**

**(d)4.41**

**(e)I think no because they obviously have like more then 1 term of something.**

** **

**6.(a) i would maybe say like 16 or 8**

**(b)x^2**

**(c)(x+4)(x+4)**

**X^2+4x+4x+16**
