Question

3) Find the remainder when 10a^2-9a-9 is divided by 5a+3​

Answer 1

Answer:

STEP

1

:

Equation at the end of step 1

((2•5a2) - 9a) - 9

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring 10a2-9a-9

The first term is, 10a2 its coefficient is 10 .

The middle term is, -9a its coefficient is -9 .

The last term, "the constant", is -9

Step-1 : Multiply the coefficient of the first term by the constant 10 • -9 = -90

Step-2 : Find two factors of -90 whose sum equals the coefficient of the middle term, which is -9 .

-90 + 1 = -89

-45 + 2 = -43

-30 + 3 = -27

-18 + 5 = -13

-15 + 6 = -9 That's it

Answer 2

Answer:

(2a−3)⋅(5a+3)

is your answer
