Question

Factor each polynomial SHOW YOUR WORK please help me x^2-9x+10 x^2+7x+10

Answer 1

Step-by-step explanation:

x²-10x+x-10

x(x-10)+1(x-10)

(x-10)(x+1)

x²+7x+10

x²+5x+2x+10

x(x+5)+2(x+5)

(x+5)(x+2).

hope this helps you.

for the first question it will be -10 .

Answer 2

Answer:

1.x^2-9x+10 answer: x=−1

x=10

work: x^2 −9x=10

Subtract 10 from both sides.

x ^2−9x−10=0

To solve the equation, factor x^2−9x−10 using formula x ^2+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.

a+b=−9

ab=−10

Since ab is negative, a and b have the opposite signs. Since a+b is negative, the negative number has greater absolute value than the positive. List all such integer pairs that give product −10.

1,−10

2,−5

Calculate the sum for each pair.

1−10=−9

2−5=−3

The solution is the pair that gives sum −9.

a=−10

b=1

To find equation solutions, solve x−10=0 and x+1=0.

x=10

x=−1

2. x^2+7x+10

answer: 4x+7
