Answer: 10%
Step-by-step explanation:
1/10 is equal to .10 or 10%
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: =
6x^2−5x−6
Step-by-step explanation: Multiply each term in one expression times each term in the other, then simplify by combining like terms.
Here are the like terms : =(3x+2)(2x−3)=3x(2x+3x(−3)+2(2x)+2(−3)
= 6x^2−9x+4x−6
=6x2−5x−6
