Question

factorise 4x²+28x+13
pls help me to solve this one please ​

Answer 1

Answer:

Factoring 4x2-28x+13

The first term is, 4x2 its coefficient is 4 .

The middle term is, -28x its coefficient is -28 .

The last term, "the constant", is +13

Step-1 : Multiply the coefficient of the first term by the constant 4 • 13 = 52

Step-2 : Find two factors of 52 whose sum equals the coefficient of the middle term, which is -28 .

-52 + -1 = -53

-26 + -2 = -28 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -26 and -2

4x2 - 26x - 2x - 13
