write each quadratic equation in standard form,aײ b× c=0 then identify the values of a,b,and c.answer the questions that follow.
1.3×-2ײ=7
2.5-2×=6×
3.(× 3)(× 4)=0
4.(2× 7)(×-1)=0
5.2×(×-3)=15
6.(× 7)(×-7)=-3×
7.(×-4)² 8=0
8.(× 2)²=3(× 2)
9.(2×-1)²=(× 1)²
10.2×(× 4)=(× 3)(×-3)


Sagot :

1. [tex]-2 x^{2} +3x=7[/tex]
[tex]-2 x^{2} +3x-7= 7-7 (APE)[/tex]
[tex]-2x^{2} +3x-7= 0[/tex]
a=-2; b=3; c= -7
3. (x+3)(x+4)=0
[tex] x^{2} [/tex]+ 4x+3x+12=0
[tex] x^{2} [/tex]+7x+12=0
a=1; b=7; c=12
5. 2x(x-3)=15
[tex] 2x^{2} [/tex] - 6x = 15
[tex] 2x^{2} [/tex] -6x-15= 15-15 (APE)
[tex] 2x^{2} [/tex] -6x-15= 0
a=2; b=-6; c=-15
yan lang po muna tinatamad ak eh :)
eh pero kung gusto nyo pa po pasagutan sakin ok lang po i'm still awake panaman :)
