Question

quick way to split middle term with 3 digits ​

Answer 1

Answer:

3x^2 + 18x +24

Step-by-step explanation:

first multiply the first and last term

then find lcm and spilit the middle term in the case when there sum is equal to middle term and multiple equals the multiple of first and last term

let see

3x^2+12x +6x+24

3x(x+4) + 6(x+4)

(3x+6)(x+4)

x=2,-4

Answer 2

$\underline{\boxed{\sf{Answer }}}\\\\\\\\116 {x}^{2} \underline{ - 88x }+ 15 = 0 \\ \\ \implies116 {x}^{2} \underline{ - 58x - 30x} + 15 = 0 \\ \\ \implies58x(2x - 1) - 15(2x - 1) = 0 \\ \\ \implies(2x - 1)(58x - 15) = 0 \\ \\ \implies(2x - 1) = 0 \: or \: (58x - 15) = 0 \\ \\ \implies \: x = \frac{1}{2} or \: x = \frac{15}{58}$
