Question

Given 4x2 – 7x = -3, what are the solutions??

Answer 1

Explanation:

4*2-7x=-3

8-7x=-3

-7x=-3-8

-7x=-11

x=-11/-7

x=1.5714...

Answer 2

• x = {3/4, 1}

Explanation:

• 4x² - 7x = -3
• 4x² - 7x + 3 = 0
• 4x² - 4x - 3x + 3 = 0
• 4x(x - 1) - 3(x - 1) = 0
• (x - 1)(4x - 3) = 0
• x - 1 = 0 | 4x - 3 = 0
• x = 1 | x = 3/4
