Question

the difference of square of two number is 88 if the larger number is 5less than twice the smaller number then find two number

Answer 1

Answer:

Step-by-step explanation:

Let the smaller number be x.

Therefore, the greater number=2x-5

From given condition,

(2x-5)the whole square -(x)square=88

4(x)square- 10x+25-(x)square=88

4(x)square-(x)square-10x=88-25

3(x)square-10x=63

3(x)square-10x-63=0

Now the remaining steps can be solved using quadratic equations

Answer 2

łєт тнє sмαłłєя ησ: вє x
тнєη тнє łαяgєя ησ: ıs 2x - 5

gıѵєη ,

(2x - 5)² - x² = 88

4x² -20x + 25 - x² = 88

3x² - 20x - 63 = 0

3x² - 27x + 7x - 63

3x(x - 9) + 7(x - 9)

(3x + 7) (x - 9)

x = -7/3 . x = 9

2x - 5 = 18 - 5 = 13
