Base a general quadratic equation in form ax² + bx + c = 0

find value of a, b and c of the equation x² - 6x + 2 = 0

• a = 1 , b = -6 , c = 2

• a = 1 , b = 6 , c = -2

• a = 0 , b = -6 , c = 2

• a = 0 , b = -6 , c = -2

In general form of quadratic equation ax² + bx + c = 0. Find the value of a, b and c on 3x² - 5x = 1

• a = 3 , b = -5 , c = 1

• a = 3 , b = -5 , c = -1

• a = -3 , b = 5 , c = 0

• a = 3 , b = -5 , c = 0

As a general form of quadratic equation ax² + bx + c = 0 determine a, b and c of 2x² = 13x + 45

• a = 2 , b = -13, c = -45

• a = 2 , b = 13, c = 45

• a = 2 , b = 13, c = -45

• a = -2 , b = -13, c = -45

In quadratic equation 2x² + 5 = 10x² by generally quadratic form ax² + bx + c = 0. Find the value of a, b and c.

• a = 12 , b = 5, c = 10

• a = 8 , b = 0, c = 5

• a = -8 , b = 0, c = 5

• a = -12 , b = 0, c = -5

The equation x ( 4 + x) = 8, if we change into general form in ax² + bx + c = 0, so the value of a, b and c are..

• a = 4 , b = 1, c = 8

• a = 1 , b = 4, c = 8

• a = 1 , b = 4, c = -8

• a = 4 , b = 1, c = -8
