Activity 4: Set Me to My Standard!
Direction: write each quadratic equation in standard form,ax²+ bx + c =0 then identify the values of a,b,and,c
1.x²- 6x- 7 = 0
2.x²- 64 = 0
3.-2x+ 8= 9x²
4.x²= 3x + 10
5.4x² - 2 = 0
6.2x(x + 1) = 0
7.(x + 4)² = 5
8.(x + 3)(x - 3) =x(4x + 5)
9.(x + 5)(x - 9) = 21
10.x(2x - 4) = (x - 2)(x - 2)

Answer:
1.x²-6x-7=0(standard form)
a=2 b=-6 c=-7 (value of a,b,c)
2.x²-64=0
a=1 b=0 c=-64
3.-9x²-2x+8=0
a=-9 b=-2 c=8
4.x²-3x-10=0
a=1 b=-3 c=-10
5.4x²-2=0
a=4 b=0 c=-2
6.2x²+2x=0
a=2 b=2 c=0
7.(x+4)(x+4)=5
x²+4x+4x+16=5
x²+8x+16=5
x²+8x+16-5=0
x²+8x+11=0
a=8 b=8 c=11
8.x²-3x+3x-9=4x²+5x
x²-9=4x²+5x
x²-4x²-5x-9=0
-3x²-5x-9=0
a=-3 b=-5 c=-9
9.x²-9x+5x-45=21
x²-4x-45=21
x²-4x-45-21=0
x²-4x-66=0
a=1 b=-4 c=-66
10.2x²-4x=x²-2x-2x+4
2x²-4x=x²-4x+4
2x²-x²-4x+4x-4=0
x²-4=0
a=1 b=0 c=-4
