4x²-17x-42
=4(x²-17/4x)-42
=4[x²-17/4 x+(-17/8)²-(-17/8)²]-42
=4(x-17/8)²-289/64-42
=4(x-17/8)²-(289+2688)/64
=4(x-17/8)²-2974/64
=[(2x-34/8)²-(√2974/8)²]
=(2x-34/8 +(√2974/8))(2x-34/8-(√2974/8)
=[2x+(√2974-34)/8][2x-(√2974+34)/8]
You can convert a fraction into a decimal by taking the numerator or the top number and such as 3/4 and the numerator would be 3 and divided it by the denominator 4 so the problem you set up should be 3 diveded by 4 which will give you .75
Its 95
Tens = 90
Ones = 5
90 + 5 = 95
