2. 7×-2ײ=2ײ
3. ×(×-12)=0
4. 1=2(ײ+3)
5. 5׳-3=4ײ
6.4x(x²+x+2)=0
7.2-x²=5x
8.(x+9)(x-13)=09
9.4x+x³=2x²
10.(x+4)(x²-4)=0

Answer 1

Answer:

Write the following in the form a×2+b×+c=0, then identify which are quadratic equations. For those that are quadratic, identify the values of a,b and c.

1. ײ-6×+10=0

2. 7×-2ײ=2ײ

3. ×(×-12)=0

4. 1=2(ײ+3)

5. 5׳-3=4ײ

6.4x(x²+x+2)=0

7.2-x²=5x

8.(x+9)(x-13)=09

9.4x+x³=2x²

10.(x+4)(x²-4)=0
