The another way to write (s - 6)(s + 1) is s² - 5s - 6
Step-by-step explanation:
Let us revise how multiply two binomial (a + b)(x + y)
- Multiply the 1st terms
- Multiply the 2nd terms
- Multiply the nears and extremes, where nears are the 2nd term of first bracket and 1st term in the second bracket, the extremes are the 1st term in the first bracket and the 2nd term in the second bracket
- Add the like terms if necessary
∵ The area of the square = (s - 6)(s + 1)
- To find the another way multiply the two brackets
∵ s × s = s²
∵ -6 × 1 = -6
∵ -6 × s = - 6s ⇒ nears
∵ s × 1 = s ⇒ extremes
- The terms - 6s and s are like terms, then add them
∵ - 6s + s = - 5s
∴ (s - 6)(s + 1) = s² - 5s - 6
∴ The area of the square = s² - 5s - 6
The another way to write (s - 6)(s + 1) is s² - 5s - 6

h(t) is the height of the diver in feet above the water
Now it asks about the time at which diver reaches the water
When diver reaches the water , the height of diver from water should be zero
So we plug h(t) =0
So
divide whole equation by -16
we can now factor the quadratic equation
So we get
(t+4)(t-3) =0
plug each factor equal to zero and solve for t
t+4 =0 and t-3 =0
So t=-4 and t=3
Now time cannot be negative , So t=3
So time = 3 seconds
It takes 3 seconds for the diver to reach the water
Answer:
x=−1 or x=−9
Step-by-step explanation:
x2+11x+10=x+1
Step 1: Subtract x+1 from both sides.
x2+11x+10−(x+1)=x+1−(x+1)
x2+10x+9=0
Step 2: Factor left side of equation.
(x+1)(x+9)=0
Step 3: Set factors equal to 0.
x+1=0 or x+9=0
x=−1 or x=−9
