Answer:
1. Standard form: 3x²-16x-12=0
Values of a, b, and c
a= 3
b= -16
c= -12
2. Standard form: 2x²-7x-30=0
a= 2
b= -7
c= -30
3. Standard form: 3x²-6x-5=0
b= -6
c= -5
4. Standard form: 5x²-3x+8=0
a= 5
b= -3
c= 8
5. Standard form: -2x²+3x-7=0
a= -2
b= 3
c= -7
6. Standard form: 4x²+7x-5=0
a= 4
b= 7
7. Standard form: 2x²-x-6=0
b= -1
c= -6
8. Standard form: x²+9x+14=0
a= 1
b= 9
c= 14
9. Standard form: 2x²+x-15=0
b= 1
c= -15
10.Standard form: 4x²-12x+9=0
b= -12
c= 9
STEP BY STEP:
HOW TO GET THE STANDARD FORM?
5. -2x²= -3x+7
transpose -3x+7 to the left side
-2x²+3x-7 — it'll look like this
6. 5-4x²+7x=0
transpose 5 to the right side
-4x+7x-5= 0 — it'll look like this
8. x²+14= -9x
transpose -9x to the left side
x²+9x+14=0 — it'll look like this
9. x-15= -2x²
transpose -2x² to the right side
2x²+x-15=0 — it'll look like this
10. 4x²= 12x-9
transpose 12x-9 to the left side
4x²-12x+9=0 — it'll look like this
NOTE:
Hope it helps you❤️
