Question

find the value of a,b and c of the following quadratic equation. 9x^2+8x-(6x2+4x-4)=2x^2+9​

Answer 1

Solution :

The given quadratic equation is -

9x² + 8x - (6x² + 4x - 4) = 2x² + 9

>> 9x² + 8x - 6x² - 4x + 4 = 2x² + 9

>> 2x² + 4x + 4 = 2x² + 9

>> 0x² + 4x - 5

Now , a general quadratic equation can be written in the form of ax² + bx + c

Comparing the coefficients of a gereral quadratic equation

a = 0, b = 4 and c = -5

Answer :

a = 0, b = 4 and c = -5
