उत्तर

The given equation is 16x2 + 24x + 9 = 0

Compare the equation to ax2 + bx + c, we get

a = 16, b = 24, c = 9

Now, we know x = `(-b +- sqrt(b^2 - 4ac))/(2a)`

= `(-24 +- sqrt((24)^2 - 4 xx 16 xx 9))/(2(16))`

= `(-24 +- sqrt(576 - 576))/32`

= `(-24 +- 0)/32`

= `(-24)/32`

= ` - 3/4`

Hence, the value of x is `- 3/4`.

Complete the following activity to solve the given quadratic equation by formula method.

2x2 + 13x + 15 = 0

Activity: 2x2 + 13x + 15 = 0

a = (______), b = 13, c = 15

b2 – 4ac = (13)2 – 4 × 2 × (______)

= 169 – 120

b2 – 4ac = 49
