The equation of tangent at those points where the curve `y=x^2-3x+2` meets x-axis are `x-y+2=0=x-y-1` (b) `x+y-1=0=x-y-2` (c) `x-y-1=0=x-y` (d) `x-y=0=x+y`

Text Solution

Verified by Experts

Given,`y=x^2−3x+2`
Let the tangent meet the x-axis at point (x,0)
⇒`dy/dx​=2x−3`
The tangent passes through point (x,0)
∴`0=x^2−3x+2=0 `
