Draw The Graph Of Y X2 3x 2 And Use It To Solve X2 2x 1 0 Mathematics Shaalaa Com
D x d y = 2 x − 2 Since the tangent line is parallel to 2 x − y 9 = 0, d x d y = slope of the straight line = 2 ⇒ 2 x − 2 = 2 ⇒ x = 2 Substituting x = 2 in the equation of the curve, we get y = 7 Hence, equation of tangent at (2, 7) with slope 2 is y − 7 = 2 (x − 2) ⇒ 2 x − y 3 = 0Steps for Solving Linear Equation y=2x2 y = 2 x 2 Swap sides so that all variable terms are on the left hand side Swap sides so that all variable terms are on the left hand side 2x2=y 2 x 2 = y Subtract 2 from both sides Subtract 2 from both sides
