Q. Which of the equations are true identities?\newlineA. (3x−2y)(2y−3x)=9x2−4y2 (3 x-2 y)(2 y-3 x)=9 x^{2}-4 y^{2} \newlineB. (2k+5r)(2k−5r)=4k2−25r2 (2 k+5 r)(2 k-5 r)=4 k^{2}-25 r^{2} \newlineChoose 11 answer:\newline(A) Only A\newline(B) Only B\newline(C) Both A and B\newline(D) Neither A nor B
  1. Expand using FOIL method: Expand the left side of equation A using the FOIL method: 3x-2y)(2y-3x)\. \$3x \cdot 2y + 3x \cdot -3x - 2y \cdot 2y - 2y \cdot -3x.
  2. Simplify the expression: Simplify the expression: 6xy−9x2−4y2+6xy6xy - 9x^2 - 4y^2 + 6xy. Combine like terms: 12xy−9x2−4y212xy - 9x^2 - 4y^2.

Rakesh tried to solve the differential equation dydx=2y⋅cos⁡(x) \frac{d y}{d x}=2 y \cdot \cos (x) . This is his work:\newlinedydx=2y⋅cos⁡(x) \frac{d y}{d x}=2 y \cdot \cos (x) \newlineStep 11: ∫1ydy=∫2cos⁡(x)dx \quad \int \frac{1}{y} d y=\int 2 \cos (x) d x \newlineStep 22: ln⁡∣y∣=2sin⁡(x) \quad \ln |y|=2 \sin (x) \newlineStep 33: eln⁡∣y∣=e2sin⁡(x) \quad e^{\ln |y|}=e^{2 \sin (x)} \newlineStep 44: ∣y∣=e2sin⁡(x) \quad|y|=e^{2 \sin (x)} \newlineStep 55: y=±e2sin⁡(x)+C \quad y= \pm e^{2 \sin (x)}+C \newlineIs Rakesh's work correct?
