Answer:
x= 0.53 and x = -0.63
Step-by-step explanation:
Quadratic formula:- ax² + bx + c
x = [-b ± √(b² - 4ac)]/2
It is given that, quadratic equation 11x2 – 4x = 1
<u>To find the value of x</u>
11x2 – 4x = 1
⇒11x2 – 4x - 1 = 0
a = 11
b = -4
c = -1
x = [-b ± √(b² - 4ac)]/2
x = [-(-4) ± √((-4)² - 4*11*-1)]/2*11
x = [4±√(16 +44)]/22
x = [4±√(60)]/22
x = [4±7.7]/22
x= 0.53 and x = -0.63
