Question

Answer of this quadratic equation
16x^2 +17x - 7

Answer 1

Answer:

Solving 16x2-17x+4 = 0 by the Quadratic Formula .

According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :

- B ± √ B2-4AC

x = ————————

2A

In our case, A = 16

B = -17

C = 4

Accordingly, B2 - 4AC =

289 - 256 =

33

Applying the quadratic formula :

17 ± √ 33

x = —————

32

√ 33 , rounded to 4 decimal digits, is 5.7446

So now we are looking at:

x = ( 17 ± 5.745 ) / 32

Two real solutions:

x =(17+√33)/32= 0.711

or:

x =(17-√33)/32= 0.352

Two solutions were found :

x =(17-√33)/32= 0.352

x =(17+√33)/32= 0.711

Answer 2

Answer:

it is incorrect ques.... u can the reason here

Step-by-step explanation:

16x²+17x-7

16x²-4x+21x-7

4x(4x-1) +7(3x-1)

it is incorrect because...in bracket bith the value must be equal but it us not equal......

therefore, the ques is wrong...
