3x² + 2x - 4 = 0
Δ = b² - 4.a.c
Δ = 2² - 4 . 3 . -4
Δ = 4 - 4. 3 . -4
Δ = 52
x = (-b +- √Δ)/2a
x' = (-2 + √52)/2.3
x'' = (-2 - √52)/2.3
x' = 0,8685170918213297
x'' = -1,5351837584879966
2 Decimal places
x' = 0,87
x'' = -1,54

Answer:
b = A / h
Step-by-step explanation:
A = b * h
Dividing the equation by h to get b on one side give us:
A / h = b * h / h
A / h = b * 1
A / h = b
b = A / h
