Factorize by splitting the middle term 6x-11x+4

Gennadij [26K]

Answer: (2x - 1)(3x - 4)

(split -11x as -8x and -3x)

Step-by-step explanation:

I am assuming that it is actually 6x^2 - 11x + 4

To find out how to split the middle term: The two numbers should multiply to a*c (6*4 = 24) and add to b (-11)

-8, -3 works

(6x^2 - 8x) + (-3x + 4)

2x(3x - 4) + -1(3x - 4)

(2x - 1)(3x - 4)

Can someone help? I don't understand.

Hence missing value in the solution to the equation is:(-5,2)

Step-by-step explanation:

We are given the equation:

$x-5y= -15$

and we need to complete the missing value in the solution to the equation

(-5,?)

Since the solution is in the form of ordered pair, so first value represent value of x and second value represents value of y i.e (x,y)

So, x= -5, Now finding y:

Putting value of x in given equation:

$x-5y= -15\\-5-5y= -15\\-5y=-15+5\\-5y=-10\\y=-10/-5\\y=2$

So, value of y is 2

Hence missing value in the solution to the equation is:(-5,2)

Which expression is a factor of x^2 + 2x – 15?

Ksju [112]

To factor this you need values that add up to 2 and multiply to -15

So you get 5,-3 then you put it into your equation for you b value

X^2+5x-3x-15

Then you can factor by grouping

X(x+5)-3(x+5)

So your factors are

(X+5)(x-3)
