Answer:
roots of equations
(1) 1/4 and 1/4
(2) 3/2 . -2
Step-by-step explanation:
(1) 2x² - x + 1/8 = 0
(16x² - 8x + 1)8 = 0
16x² - 8x + 1 = 0 × 8
16x² - 8x + 1 = 0
16x² - (4 + 4)x + 1 = 0
16x² - 4x - 4x + 1 = 0
4x(4x - 1).-1(4x - 1) = 0
(4x - 1)(4x - 1) = 0
4x - 1 = 0 . 4x - 1 = 0
4x = 1 . 4x = 1
x = 1/4 . x = 1/4
(2) 2x² + x - 6 = 0
2x² + (4 - 3)x - 6 = 0
2x² + 4x - 3x - 6 = 0
2x(x + 2).-3(x + 2) = 0
(2x - 3)(x + 2) = 0
2x - 3 = 0 . x + 2 = 0
2x = 3 . x = -2
x = 3/2 . x = -2
