Question

Solve by factorising 2x^2-3=x

Answer 1

Answer:

x = -1, 1.5

Step-by-step explanation:

Step 1: Write out equation

2x² - 3 = x

Step 2: Subtract x on both sides

2x² - 3 - x = x - x

2x² - x - 3 = 0

Step 3: Factor

(2x - 3)(x + 1) = 0

Step 4: Find roots

2x - 3 = 0

2x = 3

x = 3/2 or 1.5

x + 1 = 0

x = -1
