Use distributive property:
$(a + b)(c + d) = ac + ad + bc + cd$

$(2b+c)(3b+2c)=(2b)(3b)+(2b)(2c)+(c)(3b)+(c)(2c)\\\\=6b^2+4bc+3bc+2c^2=6b^2+7bc+2c^2$

Product? prodcut?

Mult. these 2 binomials together, using the so-called FOIL method:

6b^2 + 4bc + 3bc + 2c^2

simplify: 6b^2 + 7bc + 2c^2 (ans)

X intercept f(x)=(x+4)^2

natali 33 [55]

Answer:

Step-by-step explanation:

Given the function f(x)=(x+4)², <u>the x intercept occurs at f(x) = 0,</u> substituting f(x) = 0 into the given equation to get the value of x we have;

$0 = (x+4)^{2} \\$

Taking the square root of both sides

$\sqrt{(x+4})^{2} = \sqrt{0}\\ x+4 = 0\\$

Subtracting 4 from both sides of the equation

$x+4-4 = 0-4\\x = -4$

Therefore the x intercept of the equation is -4

Simplify 6 x 10−7 2 x 105 .

mafiozo [28]

Answer:

-49

Step-by-step explanation:

it would be this because first we would have to figure out what 6*10 is that why we know what to distribute . so once we figure it out , which is 70 . We would then subtract 14 from 70 . Since 7 is right next to 2 we would then multiply it to get to 14. Once we get that you should get 56, from there you would subtract 56 to 105 , and get your answer.
