Given the two curves y1 and y2, verify the two curves intersect at (-5,0) and (2,0)

y₁ = -3x²- 9x + 30 , y₂ = x² + 3x - 10Equate two curves ( y₁ = y₂ )Obtain following simplified quadratic: x² + 3x + 10 = 0Factorise to obtain ( x + 5 ) ( x - 2 ) = 0 and correct x values x = -5 , x = 2From x values verify y = 0 in both cases
