Manny was given the equation (x+2)(x-7)=0 and asked to find the zeros. The solutions he came up with were x=2 and x=-17.
Inessa [10]

Answer:

see explanation

Step-by-step explanation:

Given

(x + 2)(x - 7) = 0 ← in standard form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 7 = 0 ⇒ x = 7

Thus the zeros are x = - 2 and x = 7

In your own words, describe the process of multiplying binomials using the FOIL method. You can either write a paragraph describ
neonofarm [45]

Answer:

We can describe FOIL using the distributive property of multiplication. For real numbers x, y, and z the distributive property of multiplication states that

(x + y)z = xz + yz

Now let z = v + w, where v and w are real numbers.

Then (x + y)(v + w) = x(v + w) + y(v + w)

Here, we can again use the distributive property of multiplication to get

x(v + w) + y(v + w) = xv + xw + yv + yw

Hence, it follows that

(x + y)(v + w) = xv + xw + yv + yw

This is the method of FOIL (first: xv, outside: xw, inside: yv, last: yw)

For example, (1 + 2)(3 + 4) = 21 \\\text{and} \\1(3) + 1(4) + 2(3) + 2(4) = 3 + 4 + 6 + 8 = 21

SOMEBODY HELP ME IM DESPERATE
garik1379 [7]

I believe it is the commutative property of multiplication. Commutative property is you can put the numbers in any order and it will have the same end result. I got multiplication because it is multiplication.

Hope this helps!
