Select the correct answer from each drop-down menu.

Aleks [24]

Answer:

$6x^2+5x-6=(3x-2)(2x+3)$

Step-by-step explanation:

<u>Given expression</u>:

$6x^2+5x-6$

To factor a quadratic in the form $ax^2+bx+c$ , first find two numbers that multiply to $ac$ and sum to $b$ :

$\implies ac=6 \cdot -6=-36$

$\implies b=5$

Two numbers that multiply to -36 and sum to 5 are: 9 and -4

Rewrite b as the sum of these two numbers:

$\implies 6x^2+9x-4x-6$

Factorize the first two terms and the last two terms separately:

$\implies 3x(2x+3)-2(2x+3)$

Factor out the common term (2x + 3):

$\implies (3x-2)(2x+3)$

Therefore:

$6x^2+5x-6=(3x-2)(2x+3)$

If y- 18 = 14 what is the value of 3(y+5)<br>

Len [333]

<h3>Given :</h3>

$\bf y- 18 = 14$

⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

<h3>To Find :</h3>

$\bf 3(y+5) = ?$

⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

<h3>Solution :</h3>

$\bf It \: is \: given \: that \: y - 18 = 14$

$\bf \implies y = 14 + 18$

$\bf \implies y = 32$

Now, by filling value of y in 3(y+5), we get,

$\bf = 3(32 + 5)$

$\bf = 3 \times 37$

$\bf = 111$

$\pink{\bf Hence, \: the \: value \: of \: 3(y+5) \: is \: 111.}$
