Question

If x=2 is root of the poly polynomial 2 x square - 3 x + 7 a​

Answer 1

Answer:

=> 2x²-3x+7a = 0

=> 2 × 2²-3 × 2 + 7a = 0

=> 2 × 4 - 6 + 7a = 0

=> 8 - 6 + 7a = 0

=> 2 + 7a = 0

=> 7a = -2

=> a = -2/7

Answer 2

$\huge\bold\red{HOLA!!}$

Answer:

=> 2x²-3x+7a = 0

=> 2 × 2²-3 × 2 + 7a = 0

=> 2 × 4 - 6 + 7a = 0

=> 8 - 6 + 7a = 0

=> 2 + 7a = 0

=> 7a = -2

=> a = -2/7
