Answer:
(x +2) (x+3) = 0
x = -2 x = -3
Step-by-step explanation:
x^2 + 5x+ 6 = 0
To remember how to factor
key word remember word .......d. a. t. p, c
distribute x, add two no's, that also multiply, put together, change sign see below.
step 1 distribute square brackets that mean x^2 = (x ) (x )
step 2 add two numbers that add to get 5
step 3 that also multiply to get 6 = (+2) (+3) = 0
step 4 put together = (x +2) (x+3) = 0
step 5 change sign to = x = x = -2 x = -3
We have the expression:
To multiply fractions, we are going to multiply the top (straight across the top of the fraction bars) and multiply the bottom (straight across underneath the fraction bars). So then we have:
But since both the numerator and denominator are divisible by 2, we can reduce the fraction to:
So then the most simplified answer is 
.
7/22 * 11/14 = 77/308
Reduce 77/308 to get 1/4
7/22 * 11/14 = 1/4
The area with out the frame 20x24=480
the area with the frame 28x24=672
672-280=392 cm²
