Answer and Explanation:
1. 3x - 2 x²=7 ➡ 3x-2x²-7=0 ➡ -2x²+3x-7=0
A = -2
B = 3
C = -7
2. 5 - 2x² = 6x ➡ 5-2x²-6x=0 ➡ -2x²-6x+5=0
A = -2
B = -6
C = 5
3. ( X + 3 )( X + 4 ) = 0 ➡ x²+4x+3x+12=0 ➡ x²+7x+12
A = 1
B = 7
C = 12
4. ( 2x + 7 )( X - 1) = 0 ➡ 2x²-2x+7x-7=0 ➡ 2x²+5x-7=0
A = 2
B = 5
C = -7
Hindi ko na sure itong last since sobrang tagal ko na 'tong napag-aralan
5. 2x ( 3 x 3 ) = 15 ➡ 2x(9)-15=0 ➡ 18x-15
A = 0
B = 18
C = -15
