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