f'(x) = 2x - (a + b) यदि f(x) = (x - a)(x - b)
Step-by-step explanation:
f(x) = (x-a)(x-b)
f'(x) = (x-a)(x-b)' + (x-b)(x-a)'
=> f'(x) = (x - a) (1) + (x - b) (1)
=> f'(x) = x - a + x - b
=> f'(x) = 2x - a - b
=> f'(x) = 2x -(a + b)
या
f(x) = (x-a)(x-b)
f(x) = x² - bx - ax + ab
f(x) = x² - x(b + a) + ab
f(x) = x² - x(a + b) + ab
अवकलन करने पर
f'(x) = 2x - (a + b)
