Solve by completing the square:X^2+6x-12=0
Ira Lisetskai [31]
X² + 6x  -12 = 0
x = <u>-(6) +/- √((6)² - 4(1)(-12))</u>
                     2(1)
x = <u>-6 +/- √(36 + 48)</u>
                   2
x = <u>-6 +/- √(84)
</u>              2<u>
</u>x = <u>-6 +/- 2√(21)
</u>               2<u>
</u>x = -3 <u>+</u> √(21)
x = -3 + √(21)      x = -3 - √(21)

Please can someone help? As i'm not confident this is right for factorising 4b^2 + 8b + 3 ​
SIZIF [17.4K]

Answer:

your answer is correct

Step-by-step explanation:

4b² + 8b + 3

Consider the factors of the product of the coefficient of the b² term and the constant term which sum to give the coefficient of the b- term.

product = 4 × 3 = 12 and sum = + 8

The factors are 2 and 6

Use these factors to split the b- term

4b² + 2b + 6b + 3 ( factor the first/second and third/fourth terms )

= 2b(2b + 1) + 3(2b + 1) ← factor out (2b + 1) from each term

= (2b + 1)(2b + 3)
