Question

answer it 2x^2+21x-50​

Answer 1

Answer :

• 2x² + 21x - 50 = x = -2 or x = -25/2

Given :

• 2x² + 21x - 50

Solution :

》2x² + 21x - 50

》2x² + 21x - 50 = 0

》2x² - (25 + 4)x - 50 = 0

》2x² - 25x + 4x - 50 = 0

》x(2x - 25) + 2 (2x - 25) = 0

》(x + 2) (2x + 25) = 0

》x = - 2 or x = 25/2

Hence , 2x² + 21x - 50 = x = -2 or x = -25/2
